Increased pressure in the ventricles would close what valve(s)? Increased pressure in the ventricles would close what valve(s)? AV valves only semilunar valves only both semilunar and AV valves

Atrioventricular valves (AV) only

Explanation:

During the early phase of ventricular systole, when the pressure in the ventricles is increased, the atrioventricular valves (mitral/tricuspid) closes. When the pressure in the ventricles exceeds the pressure in the aorta/pulmonary trunk the aortic/pulmonary valves open and blood is pumped from the heart into the great arteries.
