Blood vessels anatomy. An artery is a blood vessel that carries blood away from the heart where it branches into ever smaller vessels. Blood vessel a vessel in the human or animal body in which blood circulates. The tunica media or a middle layer composed of elastic and muscular tissue which regulates the internal diameter of the vessel.

Blood is carried through the body via blood vessels. Arteries transport blood away from the heart and branch into smaller vessels forming arterioles. The blood vessels are the components of the circulatory system that transport blood throughout the human body.

Without oxygen and these nutrients the cells will die. Blood vessels form the living system of tubes that carry blood both to and from the heart. Bulky middle tunic contains smooth muscle and elastin 3.

Today hank explains your blood vessels and their basic three layer structure of your blood vessels. Blood is conducted through blood vessels arteries and veins. They also take waste and carbon dioxide away from the tissues.

Tutorials and quizzes on the circulation of blood and the anatomy structure and physiology of blood vessels using interactive animations and diagrams. The major systemic veins review the major systemic veins of the body including the veins of the neck arm forearm abdomen pelvis thigh and leg in this interactive tutorial. Blood pumped by the heart flows through a series of vessels known as arteries arterioles capillaries venules and veins before returning to the heart.

These vessels transport blood cells nutrients and oxygen to the tissues of the body. Aside from capillaries blood vessels are all made of three layers. Very small branches that collect the blood from the various organs and parts are called venules and they unite to form veins.

Arterioles distribute blood to capillary beds. Its smooth surface decreases resistance to blood flow. Blood is prevented from clotting in the blood vessels by their smoothness and the finely tuned balance of clotting factors.

The adventitia or outer layer which provides structural support and shape to the vessel. The vessels that carry blood away from the heart are called arteries and their very small branches are arterioles. Eventually the smallest arteries vessels called arterioles further branch into tiny capillaries where nutrients and wastes are exchanged.

All cells in the body need oxygen and the vital nutrients found in blood.
