NEET PG DENTAL EXAM

Detailed explanation-1: -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.

Detailed explanation-2: -After entering the left atrium, which then contracts and pushes the blood cell through the bicuspid, the red blood cell then enters the left ventricle. The left ventricle then contracts, pushing the red blood cell through the semi lunar, and out of the heart into the aorta.

Detailed explanation-3: -Red blood cells pick up oxygen in the lungs. Blood travels away from the heart and lungs through the arteries (ar-tuh-reez). Red blood cells drop off oxygen to the cells through tiny tubes called capillaries (cap-ill-air-ies). Blood then returns to the heart through the veins (vayns) and the cycle begins again.
