kinds of blood vessels Endothelium, 2 —> Lumen. [4] Blood vessels also transport red blood cells which contain the oxygen necessary for daily activities. All blood vessels are specifically structured to perform their function. Vasodilation is a similar process mediated by antagonistically acting mediators. As the total length of the vessel increases, the total resistance as a result of friction will increase. Systemic veins carry deoxygenated blood. Stiffened vessels may even rupture under pressure. Oxygen-poor blood enters the right side of the heart through two large veins. The blood vessels are responsible for transporting blood throughout the body. What are the main kinds of blood vessels and what functions do they preform? There are three kinds of blood vessels: arteries, veins, and capillaries. The most important types, arteries and veins, carry blood away from or towards the heart, respectively. Blood vessels are part of the circulatory system, which passes nutrients, blood, hormones, and other important substances to and from body cells in order to maintain homeostasis. arteries carry oxygen-rich blood away from the heart to all of the body's tissues. The blood vessels are the components of the circulatory system that transport blood throughout the human body. The blood space vessels are part of the circulatory system and function to transport blood throughout the body. Vessel occlusion tends to be a positive feedback system; an occluded vessel creates eddies in the normally laminar flow or plug flow blood currents. arteriovenous anastomosis: short vessel connecting an arteriole directly to a venule and bypassing the capillary beds.

Part of the series: Blood Vessels. Arteries are large blood vessels that carry blood from your heart to the rest of your … Three Kinds of Blood Vessels. Blood is circulated through the body by blood vessels via the cardiovascular system which is comprised of the heart and the circulatory system. These deposit onto the arterial walls which are already partially occluded and build upon the blockage. Aneurysms create complications by pressing against organs and may rupture and cause internal bleeding if left untreated. Without oxygen and these nutrients, the cells will die. Capilaries are where the exchange of nutrients and gasses occurs between the Each of these plays a very specific role in the circulation process. STRUCTURE AND FUNCTION OF BLOOD VESSELS In both the pulmonary and systemic circulation, blood flows through different kinds of blood vessels, each suited to its function (see Figure 8.17 and Table 8.4). The three blood vessels are called arteries, capillaries and veins. For information about plants, see, Simple diagram of the human circulatory system, Anatomy Physiology: The Unity of Form and Function, Saladin, McGraw Hill, 2012, Multiphase Flow and Fluidization, Gidaspow et al., Academic Press, 1992, List of skeletal muscles of the human body, "Blood Vessels – Heart and Blood Vessel Disorders – Merck Manuals Consumer Version", "Blood Vessel Structure and Function – Boundless Anatomy and Physiology", "Blood Vessel Diseases – Mercy Health System", https://en.wikipedia.org/w/index.php?title=Blood_vessel&oldid=995342891, Short description is different from Wikidata, Articles with unsourced statements from January 2018, Srpskohrvatski / српскохрватски, Creative Commons Attribution-ShareAlike License. This inhibits blood flow to organs and tissues and can lead to further complications such as blood clots. Blood vessel endothelium is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. These eddies create abnormal fluid velocity gradients which push blood elements such as cholesterol or chylomicron bodies to the endothelium. Blood is propelled through arteries and arterioles through pressure generated by the heartbeat. […] Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. In addition to the important role of supplying the vessel wall with nerves and self-vessels, the tunica externa helps anchor the vessels to surrounding tissues. It is also increased in inflammation in response to histamine, prostaglandins and interleukins, which leads to most of the symptoms of inflammation (swelling, redness, warmth and pain). Atherosclerosis, the formation of lipid lumps (atheromas) in the blood vessel wall, is the most common cardiovascular disease, the main cause of death in the Western world. Find out why this happens, how long it will The blood delivers oxygen and nutrients to all parts of your body and removes waste products, such as carbon dioxide. Hypertension can lead to more serious conditions such as heart failure and stroke. This comes out to about a 3000-fold range. prostaglandins), a number of hormones (e.g. The word vascular, meaning relating to the blood vessels, is derived from the Latin vas, meaning vessel. All blood vessels have the same basic structure. These are thick muscular walled and deep seated. Blood clots in deep veins lead to a condition known as deep vein thrombosis. Some structures – such as cartilage, the epithelium, and the lens and cornea of the eye – do not contain blood vessels and are labeled avascular. Very small branches that collect the blood from the various organs and parts are called venules, and they unite to form veins, which return the blood to the heart. A blood Vessel is a tubular structure that encloses and transports blood throughout the whole body of a living being. These are Arteries, Veins and Capillaries. All Arteries carry oxygenated blood except pulmonary arteries which carry deoxygenated blood to lungs for purification. Leg veins have valves which prevent backflow of the blood being pumped against gravity by the surrounding muscles.[3]. There are 3 kinds of blood vessels. Vessel networks deliver blood to all tissues in a directed and regulated manner. 'Being able to build human blood vessels as organoids from stem cells is a game changer,' said the study's senior author Josef Penninger, director of the Life Sciences Institute at the University of British Columbia. Veins are the blood vessels that carry blood from the body parts to the heart. In contrast, pressures in the venous system are constant and rarely exceed 10 mmHg. Aspirin helps prevent blood clots and can also help limit inflammation.[11]. Arteries carry oxygenated blood away from the heart. Using an advanced machine-learning algorithm and fundus eye images, which depict the small blood vessels and more at the back of the eye, investigators are … A true vessel tree structure should contain information about precise thickness of blood vessels in … The amount of red blood cells present in your vessels has an effect on your health. Blood vessels do not actively engage in the transport of blood (they have no appreciable peristalsis). In atherosclerosis, cholesterol and fatty deposits accumulate inside arterial walls leading to the formation of plaque. Septic shock and toxic shock syndrome Septic shock and toxic shock syndrome are caused by bacterial infections. Blood vessels are intricate networks of hollow tubes that transport blood throughout the entire body so that it can deliver valuable nutrients to and remove waste from cells. In the heart, this inner layer is called the endocardium. blood vessel A generic term for a tube lined by endothelium and usually invested with a muscle layer of varying thickness, which transports blood to peripheral tissues and back. ... A broken blood vessel in your eye can cause sudden redness. was posted in June 8, 2017 at 6:53 am. This is caused by an increase in the pressure of the blood flowing through the vessels. [10], The most common disease of the blood vessels is hypertension or high blood pressure. In the arterial system, this is usually around 120 mmHg systolic (high pressure wave due to contraction of the heart) and 80 mmHg diastolic (low pressure wave). In contrast, occlusion of the blood vessel by atherosclerotic plaque, by an embolised blood clot or a foreign body leads to downstream ischemia (insufficient blood supply) and possibly necrosis. Veins have a … Her work has been featured in "Kaplan AP Biology" and "The Internet for Cellular and Molecular Biologists. Higher proportions result in conditions such as dehydration or heart disease while lower proportions could lead to anemia and long-term blood loss.[5]. The largest veins are the superior and inferior vena cava, which return blood to the heart from the upper body and lower body respectively. In all veins apart from the pulmonary vein, the saturation of hemoglobin is about 75%. All cells in the body need oxygen and the vital nutrients found in blood. (with the exception of pulmonary arteries and veins which are the opposite). Depending on the health of an individual, the blood viscosity can vary (i.e. Damage, due to trauma or spontaneously, may lead to hemorrhage due to mechanical damage to the vessel endothelium. [citation needed] (The values are reversed in the pulmonary circulation.) This changes the blood flow to downstream organs, and is determined by the autonomic nervous system. Blood vessels form the living system of tubes that carry blood both to and from the heart. Arteries, Capillaries, and Veins are three kinds of blood vessels. Other kinds of shock are described below. (i) A—Artery, B—Vein, because in A lumen is narrow, in B lumen is wide. Blood vessels and surrounding structures of the kidney Non-pathological veins and arterial vessels. Permeability of the endothelium is pivotal in the release of nutrients to the tissue. Most venous problems are due to inflammation that results from an injury, blockage, defect, or infection—blood clots are commonly triggered by these. Microcirculation is the flow of blood from arterioles to capillaries or sinusoids to venules—the smallest vessels of the circulatory systemic. [1] These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. there are three main types of blood vessels: * arteries. capacitance: ability of a vein to distend and store blood. Blood vessels function to transport blood. Blood vessels are hollow tubes like pipes that carry blood through your body. Arteries—and veins to a degree—can regulate their inner diameter by contraction of the muscular layer. They also take waste and carbon dioxide away from the tissues. The vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles. The most prominent vasodilator is nitric oxide (termed endothelium-derived relaxing factor for this reason). This is also the site where carbon dioxide exits the blood. There are four main types of blood vessels that each play their own role: Arteries: These are elastic vessels that transport blood away from the heart. List the three kinds of blood vessels of human circulatory system and write their functions in tabular form. Blood travels through pulmonary and systemic circuits, the pulmonary circuit being the path between the heart and lungs and the rest of the body the systemic circuit. Veins are large blood vessels which carry blood back to the heart. The term "arterial blood" is nevertheless used to indicate blood high in oxygen, although the pulmonary artery carries "venous blood" and blood flowing in the pulmonary vein is rich in oxygen. Types Of Blood Vessels In Human Body There are three types of blood vessels present in human circulatory system. There are four main types of blood vessels that each play their own role: Blood vessels cannot function properly when inhibited by vascular diseases.

Blood vessels are needed to sustain life, because all of the body's tissues rely on their functionality.[2]. vasopressin and angiotensin) and neurotransmitters (e.g. The arteries and veins have three layers. The arteries take blood fresh with oxygen to the body from the heart. [8], Blood viscosity is the thickness of the blood and its resistance to flow as a result of the different components of the blood. There are three layers, from inside to outside: Tunica intima (the thinnest layer): a single layer of simple squamous endothelial cells glued by a polysaccharide intercellular matix, surrounded by a thin layer of subendothelial connective tissue interlaced with a number of circularly arranged elastic bands called the internal elastic lamina. capacitance vessels: veins. Atherosclerosis can also cause the bulging of a weakened artery known as an aneurysm. These include paracrine factors (e.g. The middle layer is thicker in the arteries than it is in the veins: Dub is produced by the closure of semilunar valves at the beginning of ventricular diastole. epinephrine) from the nervous system. anemia causing relatively lower concentrations of protein, high blood pressure an increase in dissolved salts or lipids, etc.). The main types of blood vessels are veins. Hematocrit tests can be performed to calculate the proportion of red blood cells in your blood. Blood Vessels helps in the transportation of blood. Blood is 92% water by weight and the rest of blood is composed of protein, nutrients, electrolytes, wastes, and dissolved gases. To prevent these diseases, the most common treatment option is medication as opposed to surgery. This all occurs in the lungs where blood is oxygenated.[7]. Blood vessels consist of arteries, arterioles, capillaries, venules, and veins. These tubes are constructed of layers of connective tissue and muscle with an inner layer formed of endothelial cells. 1. In capillaries and sinusoids, endothelium comprises the majority of the vessel. View Blood vessels.pdf from KAAP 210 at University of Delaware. Arteries move blood from the heart first to smaller arterioles, then capillaries or sinusoids, venules, veins, and back to the heart. Where is the place of 3 kinds of blood vessels? The three kinds of blood vessels found in human beings are arteries, veins and arterioles. Vasodilation and vasoconstriction are also used antagonistically as methods of thermoregulation. This page was last edited on 20 December 2020, at 14:44. Tubular structure of the circulatory system which transports blood, "Vascular" redirects here. Blood vessels play a huge role in virtually every medical condition. One of the most common diseases of the arteries is called atherosclerosis. There are various kinds of blood vessels: They are roughly grouped as "arterial" and "venous", determined by whether the blood in it is flowing away from (arterial) or toward (venous) the heart. The arteries and veins have three layers. (A) Arteries: • Arteries carry blood from heart and supply to organs. This is a result of the left and right side of the heart working together to allow blood to flow continuously to the lungs and other parts of the body. Arteries and veins are composed of three tissue layers. They’re tough on the outside but they contain a smooth interior layer of … As blood moves through capillaries, oxygen, carbon dioxide, nutrients, and waste are exchanged between blood and the fluid between cells. There are five types of blood vessels: the arteries, which carry the blood away from the heart; the arterioles; the capillaries, where the exchange of water and chemicals between the blood and the tissues occurs; the venules; and the veins, which carry blood from the capillaries back towards the heart. These small vessels that supply blood to the tissues of the vessel are called vasa vasorum, or vessels to the vessels. Cancer, for example, cannot progress unless the tumor causes angiogenesis (formation of new blood vessels) to supply the malignant cells' metabolic demand. The thick outermost layer of a vessel (tunica adventitia or tunica externa) is made of connective tissue. Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells ", Science Picture Co / Collection Mix: Subjects / Getty Images, Circulatory System: Pulmonary and Systemic Circuits, The Anatomy of the Heart, Its Structures, and Functions, How the Main Pulmonary Artery Delivers Blood to the Lungs, Types of Circulatory Systems: Open vs. Closed, Epithelial Tissue: Function and Cell Types, A.S., Nursing, Chattahoochee Technical College. Anastomoses provide critical alternative routes for blood to flow in case of blockages. This is because they are carrying the blood to and from the lungs, respectively, to be oxygenated. Blood vessel permeability is increased in inflammation. In all arteries apart from the pulmonary artery, hemoglobin is highly saturated (95–100%) with oxygen. When blood vessels connect to form a region of diffuse vascular supply it is called an anastomosis. There are various kinds of blood vessels: Arteries The circulatory system uses the channel of blood vessels to deliver blood to all parts of the body. In addition to carrying oxygen, blood also carries hormones, waste products and nutrients for cells of the body. The yellow structure coming off the kidney is the ureter. Vascular resistance occurs where the vessels away from the heart oppose the flow of blood. [8], Vessel length is the total length of the vessel measured as the distance away from the heart. Extremely small vessels located within bone marrow, the spleen, and the liver. [6] Vasoconstriction is the constriction of blood vessels (narrowing, becoming smaller in cross-sectional area) by contracting the vascular smooth muscle in the vessel walls. Regina Bailey is a board-certified registered nurse, science writer and educator. There are three major kinds of blood vessels in a human body. 2. They are easily seen on large vessels such as the aorta. The elasticity of blood vessels enables them to circulate blood but hardened plaque in arterial walls makes them too stiff to do this. Varicose veins, which are enlarged veins that can lead to blood clots, may develop when damage to vein valves causes blood to accumulate. artery: blood vessel that conducts blood away from the heart; may be a conducting or distributing vessel. Other vascular diseases include stroke, chronic venous insufficiency, and carotid artery disease. It is regulated by vasoconstrictors (agents that cause vasoconstriction). It ranges from a diameter of about 25 millimeters for the aorta to only 8 micrometers in the capillaries. [8], Vessel radius also affects the total resistance as a result of contact with the vessel wall. The arteries conduct blood away from the heart to-ward the tissue. from the heart to-ward the tissue. The middle layer is thicker in the arteries than it is in the veins: Capillaries consist of a single layer of endothelial cells with a supporting subendothelium consisting of a basement membrane and connective tissue. General Anatomy categories of the Blood of bloodvessels Vessels arteries veins t capillaries Arteries Efferentvessels carriesblood Vasculitis is inflammation of the vessel wall, due to autoimmune disease or infection. Arteries are the blood vessels that carry blood from the heart to the various parts of the body. In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. There are three main kinds of blood vessels: arteries, capillaries, and veins. Blood Vessels are the integral part of the circulatory system. The greater amount of contact with the wall will increase the total resistance against the blood flow.[9]. As the radius of the wall gets smaller, the proportion of the blood making contact with the wall will increase. Blood vessels also circulate blood throughout the circulatory system Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by the blood. Resistance is an accumulation of three different factors: blood viscosity, blood vessel length, and vessel radius. Capillaries are tiny blood vessels that connect the arterial and venous sides of circulation 2 3.The walls of these vessels are only one-cell thick to allow for easy exchange of substances in the tissues. Capillaries are the smallest of the body’s blood vessels. Various kinds of eye abnormalities are indicated by changes in vessel tree structure [5, 6]. The blood pressure in blood vessels is traditionally expressed in millimetres of mercury (1 mmHg = 133 Pa). There are 2 main kinds of blood vessels—arteries and veins (iii) Lubb is produced when ventricles contract and atrio-ventricular valves get closed at the beginning of ventricular systole. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs. List the three kinds of blood vessels of human circulatory system and write their functions in tabular form. The formation of blood clots in superficial veins can cause superficial thrombophlebitis, which is characterized by clotted veins just beneath the surface of the skin. (ii) 1 —> Endothelium, 2 —> Lumen. [4] Blood vessels also transport red blood cells which contain the oxygen necessary for daily activities. All blood vessels are specifically structured to perform their function. Vasodilation is a similar process mediated by antagonistically acting mediators. As the total length of the vessel increases, the total resistance as a result of friction will increase. Systemic veins carry deoxygenated blood. Stiffened vessels may even rupture under pressure. Oxygen-poor blood enters the right side of the heart through two large veins. The blood vessels are responsible for transporting blood throughout the body. What are the main kinds of blood vessels and what functions do they preform? There are three kinds of blood vessels: arteries, veins, and capillaries. The most important types, arteries and veins, carry blood away from or towards the heart, respectively. Blood vessels are part of the circulatory system, which passes nutrients, blood, hormones, and other important substances to and from body cells in order to maintain homeostasis. arteries carry oxygen-rich blood away from the heart to all of the body's tissues. The blood vessels are the components of the circulatory system that transport blood throughout the human body. The blood space vessels are part of the circulatory system and function to transport blood throughout the body. Vessel occlusion tends to be a positive feedback system; an occluded vessel creates eddies in the normally laminar flow or plug flow blood currents. arteriovenous anastomosis: short vessel connecting an arteriole directly to a venule and bypassing the capillary beds.

Blood is circulated through the body by blood vessels via the cardiovascular system which is comprised of the heart and the circulatory system. These deposit onto the arterial walls which are already partially occluded and build upon the blockage. Aneurysms create complications by pressing against organs and may rupture and cause internal bleeding if left untreated. Without oxygen and these nutrients, the cells will die. Capilaries are where the exchange of nutrients and gasses occurs between the Each of these plays a very specific role in the circulation process. STRUCTURE AND FUNCTION OF BLOOD VESSELS In both the pulmonary and systemic circulation, blood flows through different kinds of blood vessels, each suited to its function (see Figure 8.17 and Table 8.4). The three blood vessels are called arteries, capillaries and veins. For information about plants, see, Simple diagram of the human circulatory system, Anatomy Physiology: The Unity of Form and Function, Saladin, McGraw Hill, 2012, Multiphase Flow and Fluidization, Gidaspow et al., Academic Press, 1992, List of skeletal muscles of the human body, "Blood Vessels – Heart and Blood Vessel Disorders – Merck Manuals Consumer Version", "Blood Vessel Structure and Function – Boundless Anatomy and Physiology", "Blood Vessel Diseases – Mercy Health System", https://en.wikipedia.org/w/index.php?title=Blood_vessel&oldid=995342891, Short description is different from Wikidata, Articles with unsourced statements from January 2018, Srpskohrvatski / српскохрватски, Creative Commons Attribution-ShareAlike License. This inhibits blood flow to organs and tissues and can lead to further complications such as blood clots. Blood vessel endothelium is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. These eddies create abnormal fluid velocity gradients which push blood elements such as cholesterol or chylomicron bodies to the endothelium. Blood is propelled through arteries and arterioles through pressure generated by the heartbeat. […] Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. In addition to the important role of supplying the vessel wall with nerves and self-vessels, the tunica externa helps anchor the vessels to surrounding tissues. It is also increased in inflammation in response to histamine, prostaglandins and interleukins, which leads to most of the symptoms of inflammation (swelling, redness, warmth and pain). Atherosclerosis, the formation of lipid lumps (atheromas) in the blood vessel wall, is the most common cardiovascular disease, the main cause of death in the Western world. Find out why this happens, how long it will The blood delivers oxygen and nutrients to all parts of your body and removes waste products, such as carbon dioxide. Hypertension can lead to more serious conditions such as heart failure and stroke. This comes out to about a 3000-fold range. prostaglandins), a number of hormones (e.g. The word vascular, meaning relating to the blood vessels, is derived from the Latin vas, meaning vessel. All blood vessels have the same basic structure. These are thick muscular walled and deep seated. Blood clots in deep veins lead to a condition known as deep vein thrombosis.

'Being able to build human blood vessels as organoids from stem cells is a game changer,' said the study's senior author Josef Penninger, director of the Life Sciences Institute at the University of British Columbia. Veins are the blood vessels that carry blood from the body parts to the heart. In contrast, pressures in the venous system are constant and rarely exceed 10 mmHg. Aspirin helps prevent blood clots and can also help limit inflammation.[11]. Arteries carry oxygenated blood away from the heart. Using an advanced machine-learning algorithm and fundus eye images, which depict the small blood vessels and more at the back of the eye, investigators are … A true vessel tree structure should contain information about precise thickness of blood vessels in … The amount of red blood cells present in your vessels has an effect on your health. Blood vessels do not actively engage in the transport of blood (they have no appreciable peristalsis). In atherosclerosis, cholesterol and fatty deposits accumulate inside arterial walls leading to the formation of plaque. Septic shock and toxic shock syndrome Septic shock and toxic shock syndrome are caused by bacterial infections. Blood vessels are intricate networks of hollow tubes that transport blood throughout the entire body so that it can deliver valuable nutrients to and remove waste from cells. In the heart, this inner layer is called the endocardium. blood vessel A generic term for a tube lined by endothelium and usually invested with a muscle layer of varying thickness, which transports blood to peripheral tissues and back. ... A broken blood vessel in your eye can cause sudden redness. was posted in June 8, 2017 at 6:53 am. This is caused by an increase in the pressure of the blood flowing through the vessels. [10], The most common disease of the blood vessels is hypertension or high blood pressure. In the arterial system, this is usually around 120 mmHg systolic (high pressure wave due to contraction of the heart) and 80 mmHg diastolic (low pressure wave). In contrast, occlusion of the blood vessel by atherosclerotic plaque, by an embolised blood clot or a foreign body leads to downstream ischemia (insufficient blood supply) and possibly necrosis. Veins have a … Her work has been featured in "Kaplan AP Biology" and "The Internet for Cellular and Molecular Biologists. Higher proportions result in conditions such as dehydration or heart disease while lower proportions could lead to anemia and long-term blood loss.[5]. The largest veins are the superior and inferior vena cava, which return blood to the heart from the upper body and lower body respectively. In all veins apart from the pulmonary vein, the saturation of hemoglobin is about 75%. All cells in the body need oxygen and the vital nutrients found in blood. (with the exception of pulmonary arteries and veins which are the opposite). Depending on the health of an individual, the blood viscosity can vary (i.e. Damage, due to trauma or spontaneously, may lead to hemorrhage due to mechanical damage to the vessel endothelium. [citation needed] (The values are reversed in the pulmonary circulation.) This changes the blood flow to downstream organs, and is determined by the autonomic nervous system. Blood vessels form the living system of tubes that carry blood both to and from the heart. Arteries, Capillaries, and Veins are three kinds of blood vessels. Other kinds of shock are described below. (i) A—Artery, B—Vein, because in A lumen is narrow, in B lumen is wide. Blood vessels and surrounding structures of the kidney Non-pathological veins and arterial vessels. Permeability of the endothelium is pivotal in the release of nutrients to the tissue. Most venous problems are due to inflammation that results from an injury, blockage, defect, or infection—blood clots are commonly triggered by these. Microcirculation is the flow of blood from arterioles to capillaries or sinusoids to venules—the smallest vessels of the circulatory systemic. [1] These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. there are three main types of blood vessels: * arteries. capacitance: ability of a vein to distend and store blood. Blood vessels function to transport blood. Blood vessels are hollow tubes like pipes that carry blood through your body. Arteries—and veins to a degree—can regulate their inner diameter by contraction of the muscular layer. They also take waste and carbon dioxide away from the tissues. The vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles. The most prominent vasodilator is nitric oxide (termed endothelium-derived relaxing factor for this reason). This is also the site where carbon dioxide exits the blood. There are four main types of blood vessels that each play their own role: Arteries: These are elastic vessels that transport blood away from the heart. List the three kinds of blood vessels of human circulatory system and write their functions in tabular form. Blood travels through pulmonary and systemic circuits, the pulmonary circuit being the path between the heart and lungs and the rest of the body the systemic circuit. Veins are large blood vessels which carry blood back to the heart. The term "arterial blood" is nevertheless used to indicate blood high in oxygen, although the pulmonary artery carries "venous blood" and blood flowing in the pulmonary vein is rich in oxygen. Types Of Blood Vessels In Human Body There are three types of blood vessels present in human circulatory system. There are four main types of blood vessels that each play their own role: Blood vessels cannot function properly when inhibited by vascular diseases.
