What are the features of the structure and function of the arteries?

Arteries are large blood vessels. They are essential for the transport of arterial blood. Venous and arterial blood are one and the same fluid, just at certain stages its composition changes. The names come from the names of the blood vessels. Arterial blood is enriched with oxygen. It leaves the heart through the arteries. Arteries diverge into many capillaries in various tissues and organs. So the body provides itself with sufficient oxygen. Then, the capillaries pass into the veins.
