Arteries are muscular blood vessels that carry oxygenated blood away from the heart
Capillaries are the smallest of a body's blood vessels, which connect arterioles and venules, and are important for the interchange of oxygen, carbon dioxide, and other substances between blood and tissue cells.
Veins are blood vessel that usually carry deoxygenated blood toward the heart

Arteries carry oxygen rich blood away from the heart towards the rest of the body. Veins carry oxygen depleted blood back to the heart. Capillaries are small vessels which connect the arteries and veins.
Try finding anatomy pictures because it is easier to understand when you visualize it.

Arteries are muscular blood vessels that carry blood away from the heart.[1] All arteries, with the exception of the pulmonary and umbilical arteries, carry oxygenated blood.
Capillaries are the smallest of a body's blood vessels, measuring 5-10 μm in diameter, which connect arterioles and venules, and are important for the interchange of oxygen, carbon dioxide, and other substances between blood and tissue cells.
vein is a blood vessel that carries blood toward the heart. The majority of veins in the body carry low-oxygen blood from the tissues back to the heart; the exceptions being the pulmonary and umbilical veins which both carry oxygenated blood.

An artery is a blood vessel that carries blood away from the heart. Memory trick: arteries away.
A vein is a blood vessel that carries blood back to the heart.
Capillaries are the tiniest blood vessels that connect the arteries to the veins. The capillaries exchange materials between the bloodstream and the body's cells.
