For knowing more about Artificial Blood Vessel
The blood vessels are the components of the circulatory system that carry blood around the human body. These vessels carry blood cells, nutrients and oxygen to the tissues of the body. They also take waste and carbon dioxide out of the tissues. Blood vessels are needed to sustain life because all tissues in the body depend on their functionality.
There are five types of blood vessels: the arteries that carry blood away from the heart; the arterioles; the capillaries, in which the exchange of water and chemicals between blood and tissues takes place; the venules; and the veins that carry blood from the capillaries back to the heart.
Blood vessels are used to transport blood. In general, arteries and arterioles carry oxygenated blood from the lungs to the body and its organs, and veins and venules carry oxygen-depleted blood from the body to the lungs. Blood vessels also circulate blood throughout the circulatory system. Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient that the blood carries. In all arteries except the pulmonary artery, hemoglobin is highly saturated with oxygen (95–100%). In all veins except the pulmonary vein, hemoglobin saturation is approximately 75%. [Citation required] (The values in the pulmonary circulation are reversed.) In addition to transporting oxygen, blood also contains hormones, waste products and nutrients for the cells in the body.
Blood vessels are not actively involved in blood transport (they have no noticeable peristalsis). The pressure created by the heartbeat drives blood through arteries and arterioles. Blood vessels also carry red blood cells, which contain the oxygen necessary for daily activities. The amount of red blood cells in your blood vessels affects your health. Hematocrit tests can be done to calculate the percentage of red blood cells in your blood. Higher values lead to conditions such as dehydration or heart disease, while lower values can lead to anemia and long-term blood loss.
