What term names the heart's main pumping chambers?

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

Answer: (D)

Ventricles are the heart's main pumping chambers. They have thick muscular walls to generate the high pressure needed to push blood to the lungs (right ventricle) and to the rest of the body (left ventricle). The atria are receiving chambers, collecting blood and passing it to the ventricles, but they don’t propel blood out of the heart. The septum is the wall that divides the heart into left and right sides, and valves control one-way blood flow. So, the term that names the heart’s main pumping chambers is ventricles.
