Arteries

carry oxygenated blood from the heart (except the pulmonary)

Aorta

the primary artery of the body

Veins

carry deoxygenated blood towards the heart

Vena Cava

the primary vein of the body

Vein valves

help prevent the backflow of blood

varicose veins

the damaging of the vein valves

capillaries

O₂ and CO₂ gas exchanged along the concentration gradient (diffusion)
