What is the Valvular Response to the Contraction of the Ventricles

Question

What is the valvular response to the contraction of the ventricles?
A) The AV valves open.
B) The semilunar valves close.
C) The pulmonic and aortic valves open.
D) The entrance valves open.

Accepted Answer

When the ventricles contract, the pressure inside them increases, forcing the pulmonic and aortic valves to open, allowing blood to be ejected into the pulmonary and systemic circulation. At the same time, the AV valves close to prevent backflow into the atria.
