Question 1

During the cardiac cycle,what makes the aortic and pulmonic valves close after the ventricles contract?

Accepted Answer

A)  The papillary muscles relax,which allows the valves to close. 
B)  Chordae tendineae contract,which pulls the valves closed. 
C)  Reduced pressure in the ventricles creates a negative pressure,which pulls the valves closed. 
D)  Blood fills the cusps of the valves and causes the edges to merge,closing the valves.

Question 6

During the cardiac cycle,what makes the mitral and tricuspid valves close after the ventricles are filled with blood?

Accepted Answer

A)  The chordae tendineae relax,which allows the valves to close. 
B)  The increased pressure in the ventricles pushes the values to close. 
C)  The trabeculae carneae contract,which pulls the valves closed. 
D)  The reduced pressure in the atria creates a negative pressure that pulls the valves closed.
