What are the chambers in the heart that pump blood referred to as?

• A. Atria
• B. Ventricles
• C. Valves
• D. Septum

Answer: (B)

The chambers of the heart that are responsible for pumping blood are known as ventricles. The heart consists of four chambers: the right and left atria, and the right and left ventricles. While the atria receive blood from the body and lungs, it is the ventricles that pump blood out of the heart. The right ventricle sends deoxygenated blood to the lungs for oxygenation, and the left ventricle pumps oxygenated blood to the rest of the body. This distinction is crucial in understanding the heart's function in the circulatory system, as the effective pumping action of the ventricles is vital for maintaining blood flow and circulation throughout the body. The other terms refer to different structures in the heart: atria are the chambers that collect blood; valves regulate blood flow between the chambers and the arteries; and the septum is the wall that separates the left and right sides of the heart.
