Aorta

The largest artery in the body. It carries blood away from the heart. It arises from the left ventricle of the heart, forms an arch, then extends down to the abdomen, where it branches off into two smaller arteries.

Tricuspid valve

The first valve that blood flows through in the heart. It is one of the two atrioventricular valves, meaning that it is located between the atrium and the ventricle, in this case, on the right side of the heart. It is made of three flaps, or leaflets, that work together to stop and start the flow of blood.

Pulmonary Valve

The second valve of the heart. Like the aortic valve, it is also referred to as a semilunar valve, because of its shape. It lies b/w the right ventricle and the pulmonary artery, which takes blood to the lungs.

Aortic Valve

The fourth and final heart valve, lying b/w the left ventricle and the aorta. The valve is composed of three leaflets, working together to stop blood from entering the aorta prematurely.

Bicuspid valve

Or mitral valve, is the third valve of the heart. It is also an atrioventricular valve, meaning it rests b/w the left atrium and the left ventricle. Oxygenated blood passes through the mitral valve.

Inferior vena cava

one of the two large blood vessels that carry deoxygenated blood to the right atrium.

Superior vena cava

the other large blood vessels that carry deoxygenated blood to the right atrium located superior to the atrium.

Left atrium

It receives oxygenated blood from the lungs and pumps it down the left ventricle.

Right atrium

It receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle.

Left Pulmonary veins

Carry the oxygenated blood from the left lung to the left atrium.

Right Pulmonary veins

Carry the oxygenated blood from the right lung to the left atrium.

Left ventricle

One of the four chambers in the human heart. It receives oxygenated blood from the left atrium via the mitral valve/ bicuspid valve.

Right ventricle

One of four chambers in the human heart. It receives deoxygenated blood from the right atrium via the tricuspid valve.

septum

The stout wall separating the lower chambers (the ventricles) of the heart from one another.

Descending Aorta

It's a part of the aorta, the largest artery in the body. It is the part of the aorta beginning at the aortic arch that runs down through the chest and abdomen.

Pulmonary Trunk

A vessel that arises from the right ventricle of the heart, extends upward, and divides into the right and left pulmonary arteries that take the deoxygenated blood to the lungs.

Left Pulmonary Artery

It carries deoxygenated blood to the left lung from the pulmonary trunk.

Right Pulmonary Artery

It carries deoxygenated blood to the right lung from the pulmonary trunk.
