Exam is closed notes and no communication with any neighboring or outside entity is allowed. Multiple Choice Questions (3 points each). In each of the following questions choose the best answer. Consider the following pressure volume loop for the left ventricle. 1. During the B to C segment, A. Only the mitral valve is open B. Only the aortic valve is open C. Both valves are closed D. Both valves are open E. None of the above 2. During the C to D segment, A. Only the mitral valve is open B. The mitral and aortic valve are open C. Only the aortic valve is open D. Both the aortic and mitral valves are closed E. None of the above Name: __________________________________ 2. During the D to A segment, A. Only the aortic valve is open B.
