PATHOLOGY

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: -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. From the left atrium blood flows into the left ventricle.

Detailed explanation-3: -The pulmonary artery carries blood to the lungs where it takes up oxygen. Oxygenated blood returns to the heart through the pulmonary vein into the left atrium. The blood then moved through the mitral valve into the left ventricle. The left ventricle then pumps the blood through the aortic valve into the aorta.
