Answer to Question 1

ANS: C
As the ventricles empty, the ventricular pressures decrease, allowing closure of the aortic and pulmonic valves, producing the second heart sound, S2. The mitral and tricuspid produce the first heart sound, S1. The aortic and mitral do not close at the same time. The mitral and pulmonic do not close at the same time.

Answer to Question 2

ANS: C
The blood flows through the valves in the following direction: tricuspid, pulmonic, mitral, and aortic.
