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: -When blood leaves the heart to go to the rest of the body, it travels through a large artery called the aorta. A balloon-like bulge, called an aortic aneurysm, can sometimes occur in the aorta.

Detailed explanation-3: -Oxygen-rich blood travels from your lungs to your left atrium through large veins called pulmonary veins. Your mitral valve opens to send blood from your left atrium to your left ventricle.

Detailed explanation-4: -Most arteries carry oxygenated blood, and most veins carry deoxygenated blood; the pulmonary arteries and veins are the exceptions to this rule.

Detailed explanation-5: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
