The (14) atrium receives blood as it returns from the body cells. The right (15) receives blood from the right atrium and pumps blood into the pulmonary artery, which carries the blood to the lungs for oxygen. The left (16)atrium receives oxygenated blood from the lungs. The (17) ventricle receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells.

Answer:
(14) What is the function of the atrium in the heart?
The atrium in the heart functions to receive blood as it returns from the body cells. It does not pump blood but instead acts as a receiving chamber.
(15) What is the function of the right ventricle in the heart?
The right ventricle in the heart receives blood from the right atrium and pumps it into the pulmonary artery, which carries the blood to the lungs for oxygenation.
(16) What is the function of the left atrium in the heart?
The left atrium in the heart receives oxygenated blood from the lungs and prepares it for pumping into the left ventricle.
(17) What is the function of the left ventricle in the heart?
The left ventricle in the heart receives blood from the left atrium and pumps it into the aorta for transport to the body cells. This ventricle has thicker walls than the right ventricle because it needs to generate a higher force to pump blood to the entire body, while the right ventricle only pumps to the lungs.
