Question

Name the blood vessels which have valves. What is the purpose of these valves

Answer 1

Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong thatblood is only able to flow in one direction.)Valves also help blood travel back to the heart against the force of gravity.

➡️Veins are blood vessels that carry blood from the body back to the heart.

➡️Blood return from the legs occurs mainly through the deep veins. Within the veins, especially those of the legs are valves.

➡️Venous valves are bicuspid (two) flap like structures made of elastic tissue.
