What arteries veins arterioles venules and capillaries?
Blood vessels are found throughout the body. There are five main types of blood vessels: arteries, arterioles, capillaries, venules and veins. Arteries carry blood away from the heart to other organs.

Capillaries lead back to small vessels known as venules that flow into the larger veins and eventually back to the heart.
