Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body. They also take waste and carbon dioxide away from the tissues. [2] Some tissues such as cartilage, epithelium, and the lens and cornea of the eye are not supplied with blood vessels and are termed avascular.
If a blood vessel breaks, tears, or is cut, blood leaks out, causing bleeding. Blood may flow out of the body, as external bleeding, or it may flow into the spaces around organs or directly into organs, as internal bleeding.
Blood vessels are also involved in circulating both oxygenated (poor) and deoxygenated (impure) blood from and to the heart. Blood vessels help in the transportation of nutrients, water, minerals, hormones and all other essential components required for the different body metabolism.
