Final answer:
True. The atria are the receiving chambers of the heart, receiving incoming blood, while the ventricles are the pumping chambers that send blood out of the heart to the lungs and body.
Step-by-step explanation:
The statement that the receiving chambers of the heart are the atria, and the forcefully pumping chambers of the heart are the ventricles is True. The heart is made up of four chambers: two atria (singular, atrium) on the top and two ventricles on the bottom. The atria are referred to as receiving chambers because they receive blood; the right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs.
The ventricles are the primary pumping chambers, sending blood out of the heart; the right ventricle sends blood to the lungs for oxygenation, and the left ventricle pumps oxygenated blood to the systemic circuit to supply the body.
