MEDICAL PHYSIOLOGY

Detailed explanation-1: -The 2 upper chambers are the atria. They receive and collect blood. The 2 lower chambers are the ventricles. They pump blood to other parts of your body.

Detailed explanation-2: -Right ventricle: Receives blood from the right atrium; pumps blood into the pulmonary artery.

Detailed explanation-3: -The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs.

Detailed explanation-4: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.
