Arteries are blood vessels that transport blood away from the heart to the body. They are the largest blood vessels in the body and have thick elastic walls.
Capillaries are blood vessels that carry blood away from body and exchange waste, nutrients, and oxygen with cells or tissues. Capillaries are smallest blood vessels and their walls contain only a single layer of tissues.
Veins are blood vessels that transport the blood from the body to the heart. Veins have less connective and smooth muscle tissue that make veins' walls thinner that walls of arteries.
