Veins and arteries
Veins
These are blood vessels that take blood back to the heart; this blood lacks oxygen and is rich in waste products that are to be excreted or removed from the body. Veins become larger and larger as they get closer to the heart.
Arteries
They begin with the aorta, the large artery leaving the heart. Arteries carry oxygen-rich blood away from the heart to all of the body's tissues. They branch several times, becoming smaller and smaller as they carry blood farther from the heart.
Heart
Function
muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.
location
between the lungs, in the middle compartment of the chest.
Valves
Blood passes through a valve before leaving each chamber of the heart. The valves prevent the backward flow of blood.
