ANATOMY

Detailed explanation-1: -The left ventricle (LV) pumps the oxygen-rich blood through the aortic valve (AoV) into the aorta (Ao), the main artery that takes oxygen-rich blood out to the rest of the body.

Detailed explanation-2: -The heart has four chambers-two on top and two on bottom: The two bottom chambers are the right ventricle and the left ventricle. These pump blood out of the heart. A wall called the interventricular septum is between the two ventricles.

Detailed explanation-3: -The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygen-rich blood to the body.

Detailed explanation-4: -It returns to the heart and enters the left atrium. From there, blood is forced through the mitral valve into the left ventricle. This is the muscular pump that sends blood out to the rest of the body. When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta.

Detailed explanation-5: -systole-this is when your heart contracts, pushing blood out of the chambers.
