What are the functional differences between veins and arteries?
What other differences are there between veins and arteries?
One of the main differences is the thickness of their walls. Arteries have thick elastic walls, to cope with the high pressure of blood pumped from the heart. Veins, on the other hand, have thin walls and less elasticity, as they work under lower pressure. Additionally, veins have one-way valves to prevent the backflow of blood, whereas arteries do not.
