NEET PG DENTAL EXAM

Detailed explanation-1: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. 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.

Detailed explanation-2: -The heart pumps deoxygenated blood from the right ventricle to the lungs and at the same time pumps oxygenated blood from the left ventricle into the aorta.

Detailed explanation-3: -There are four chambers: the left atrium and right atrium (upper chambers), and the left ventricle and right ventricle (lower chambers). The right side of your heart collects blood on its return from the rest of your body. The blood entering the right side of your heart is low in oxygen.
