To review:
The side of the heart that receives and pumps deoxygenated blood.
Introduction:
The human heart is a four-chambered organ that is roughly the size of a man’s closed fist. The heart is made up of cardiac muscles that are continuously in a rhythmic motion. It acts like a pump that receives deoxygenated blood and sends it to the lungs for purification. It receives oxygenated blood from the lungs and distributes it to the other organs of the body.
Explanation of Solution
The right side of the heart is on the receiving end of the deoxygenated blood arriving from the vena cava and pumps it to the pulmonary vein. The right ventricle obtains deoxygenated blood from the right atrium. The left ventricle is supplied with oxygenated blood from the left atrium and sends it to the aorta.
The right side of the heart which includes the right atrium and the right ventricle is responsible for pumping blood to the lungs. The heart pumps the blood to all organs and tissues. The right ventricle pumps blood to the lungs where it becomes oxygenated. The right atrium receives and holds deoxygenated blood from systemic veins.
