How can you tell the difference between an artery and a vein?

One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas, veins carry the deoxygenated blood to the heart.

What are the main differences between arteries veins and capillaries?

Capillaries consist of a single layer of epithelial cells, the endothelium tunic (tunica intima). Veins and arteries both have two further tunics that surround the endothelium: the middle, tunica media is composed of smooth muscle, while the outer tunica externa is connective tissue (collagen and elastic fibers).

How can you tell the difference between an artery and a vein in cadaver?

Veins have relatively thin walls that collapse easily; arteries have thicker walls and are round and lighter in color.

What are the similarities between an artery and a vein?

Veins carry the blood back to the heart. They're similar to arteries but not as strong or as thick. 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 that blood is only able to flow in one direction.)
