What is the function of blood vessel?

Answer 1

The function of blood vessels is to carry blood around the body. Blood vessels are the passageway of blood. They are found all over your body. When any blood vessel is punctured or cut,blood flows out.

There are three kinds of blood vessels in the human body. These are arteries,the veins, and the capillaries.
