Heart System

The right atrium receives deoxygenated blood from the body through the inferior and superior vena cavae.

The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

The aorta is the main artery that carries oxygenated blood from the left ventricle to the rest of the body.

Deoxygenated blood is blood that is low in oxygen and high in carbon dioxide, returning to the heart from the body.

The tricuspid valve controls blood flow from the right atrium to the right ventricle.

The left ventricle pumps oxygenated blood to the body, while the right ventricle pumps deoxygenated blood to the lungs.

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation.

Valves prevent the backflow of blood and ensure it flows in one direction through the heart.

The superior vena cava carries deoxygenated blood from the upper body to the right atrium.

The septum separates the left and right sides of the heart, preventing mixing of oxygenated and deoxygenated blood.
