kinds of blood vessels

They also take waste and carbon dioxide away from the tissues. (with the exception of pulmonary arteries and veins which are the opposite). Arteries and veins are composed of three tissue layers. [8], Vessel radius also affects the total resistance as a result of contact with the vessel wall. In the heart, this inner layer is called the endocardium. Resistance is an accumulation of three different factors: blood viscosity, blood vessel length, and vessel radius. (A) Arteries: • Arteries carry blood from heart and supply to organs. There are three main kinds of blood vessels: arteries, capillaries, and veins. 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. [8], Vessel length is the total length of the vessel measured as the distance away from the heart. It ranges from a diameter of about 25 millimeters for the aorta to only 8 micrometers in the capillaries. Arteries move blood from the heart first to smaller arterioles, then capillaries or sinusoids, venules, veins, and back to the heart. List the three kinds of blood vessels of human circulatory system and write their functions in tabular form. The middle layer is thicker in the arteries than it is in the veins: 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. Veins have a … In all veins apart from the pulmonary vein, the saturation of hemoglobin is about 75%. [8], Blood viscosity is the thickness of the blood and its resistance to flow as a result of the different components of the blood. 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. As blood moves through capillaries, oxygen, carbon dioxide, nutrients, and waste are exchanged between blood and the fluid between cells. They are easily seen on large vessels such as the aorta. 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 … 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). 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. These tubes are constructed of layers of connective tissue and muscle with an inner layer formed of endothelial cells. One of the most common diseases of the arteries is called atherosclerosis. Blood vessel endothelium is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. These small vessels that supply blood to the tissues of the vessel are called vasa vasorum, or vessels to the vessels. Each of these plays a very specific role in the circulation process.

The size of blood vessels is different for each of them. These include paracrine factors (e.g. 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. The blood pressure in blood vessels is traditionally expressed in millimetres of mercury (1 mmHg = 133 Pa). The three kinds of blood vessels found in human beings are arteries, veins and arterioles. Various kinds of eye abnormalities are indicated by changes in vessel tree structure [5, 6]. The arteries and veins have three layers. [citation needed] (The values are reversed in the pulmonary circulation.) Arteries are the blood vessels that carry blood from the heart to the various parts 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. Damage, due to trauma or spontaneously, may lead to hemorrhage due to mechanical damage to the vessel endothelium. Leg veins have valves which prevent backflow of the blood being pumped against gravity by the surrounding muscles.[3].
