Aorta the body's largest artery. Takes oxygenated blood from the left ventricle to the body.

Pulmonary Artery carries deoxygenated blood from the right ventricle to the lungs.

Oxygenated blood carrying oxygen

Deoxygenated blood carrying little or oxygen

Right Atrium
Receives deoxygenated blood from the body

Pulmonary Vein
Takes oxygenated blood from the lungs to the left atrium

Left Ventricle
Pumps oxygenated blood into the aorta

Right Ventricle pumps deoxygenated blood into the pulmonary artery

Coronary Vessels supply the heart muscle with its blood supply

Arteries
Carry the blood AWAY from the heart

Veins
Carry the blood TOWARDS the heart

Bicuspid Valve valve between the left atrium and the left ventricle.

Tricuspid Valve valve between the right atrium an the right ventricle.

Vena Cava the largest vein in the body, it carries blood from the body back to the heart.

Similarities
Like a human heart, a pig heart consists of four chambers: two atriums and two ventricles. Likewise, consistent with the structure of a human heart, it has four valves and an aorta. These similarities allow blood to flow through a pig’s heart in the same way it flows through a human’s heart. In fact, pig hearts are so similar to human hearts that tissue from pig hearts is used to make heart valve replacements for humans. Of course, the tissue is treated before surgery to decrease the likelihood of the recipient’s immune system rejecting it.
