Where are your main veins located?

Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart. Deep veins, located in the center of the leg near the leg bones, are enclosed by muscle. The iliac, femoral, popliteal and tibial (calf) veins are the deep veins in the legs.

Pulmonary veins carry oxygenated blood towards the heart and the pulmonary arteries carry deoxygenated blood away from the heart.
