Detailed explanation-1: -Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber. 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 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. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
Detailed explanation-3: -Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Detailed explanation-4: -Usually the blood is oxygenated; the exceptions are the pulmonary arteries, which carry blood away from the heart to the lungs to become oxygenated. Veins carry deoxygenated blood towards to heart from tissue, with the exception of the pulmonary veins, which carry oxygenated blood from the lungs to the heart.
