The pump in the lab activity simulates which cardiac structure?

• A. Right ventricle
• B. Left ventricle
• C. Left atrium
• D. Right atrium

Answer: (B)

The left ventricle is the heart’s strong pump that pushes blood into the systemic circulation, generating high pressures to overcome systemic vascular resistance. In cardiovascular dynamics lab setups, the pump is typically arranged to reproduce this high-pressure, pulsatile ejection into the systemic circuit, which matches the left ventricle’s role. The other chambers operate at much lower pressures: atria mainly receive blood with modest pressure, and the right ventricle pumps to the lungs at relatively low pressures. So the pump best represents the left ventricle because it embodies that high-pressure, systemic-ejection function.
