ANATOMY

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: -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: -The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body. Blood travels through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it through the tricuspid valve to the right ventricle.

Detailed explanation-4: -Thus the right side of the heart carries deoxygenated blood and the left side of the heart carries oxygenated blood.

Detailed explanation-5: -The left ventricle collects oxygenated blood out of the left atrium to further distribute it to the aorta. Oxygenated blood is found in the left side ( left atrium and left ventricle) of the heart.
