What do the 4 cambers of heart do?

1. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava. The superior vena cava receives blood from the upper body, while the inferior vena cava receives blood from the lower body.

2. The right ventricle pumps deoxygenated blood to the lungs through the pulmonary artery. The pulmonary artery divides into two branches, one leading to each lung.

3. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. The pulmonary veins carry oxygenated blood from the lungs to the heart.

4. The left ventricle pumps oxygenated blood to the body through the aorta. The aorta is the largest artery in the body and carries oxygenated blood to all tissues and organs.
