Capillaries are considered separately from veins. They are the smallest vessels in the circulatory system. Exchange of oxygen and carbon dioxide occur through them. Also wastes and nutrients.
Veins carry deoxygenated blood from systemic circulation back to your heart. Capillaries are the small blood vessels that transfer blood between arteries and veins. The capillaries supply the cells with nutrients, fluids and oxygen. Capillaries also remove carbon dioxide.
