MEDICAL PHYSIOLOGY

Detailed explanation-1: -The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.

Detailed explanation-2: -Your mitral valve opens to send blood from your left atrium to your left ventricle. When your left ventricle is full it squeezes, which closes your mitral valve and opens your aortic valve. Your heart sends blood through your aortic valve to your aorta, where it flows to the rest of your body.

Detailed explanation-3: -The aorta carries oxygenated blood from the left ventricle (one of your heart’s four chambers) to the rest of your body. The ascending aorta is the first part closest to your heart. This portion has two small branches. These are the major coronary arteries that supply oxygen-rich blood to the heart muscle.
