Detailed explanation-1: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
Detailed explanation-2: -Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium.
Detailed explanation-3: -The right side of the heart pumps oxygen-poor blood from the body to the lungs, where it receives oxygen. The left side of the heart pumps oxygen-rich blood from the lungs to the body. Once the body’s organs and tissues have removed the oxygen from the blood, the blood returns to the heart.
