Question

There is a phase of cardiac cycle during which the ventricular muscle fibers are contracting, but, not actively shortening. The volume of blood in the chamber remains the same. The Mitral and Aortic valves are closed. This phase is During the phase of mid ventricular diastole/Relaxation phase, the atria and ventricles are in diastole, blood flows passively from atria into the ventricles. (true/False) During Late ventricular diastole: Atria are relaxing/in Diastole Ventricles are contracting/in systole Atria are contracting/in systole Aorta is in systole in Left ventricular systole (Ejection phase) Compare the pressures in Left ventricle and Left atrium. Which is higher? Compare the pressures in Left ventricle and Aorta, which pressure is higher? Where is blood from the ventricle moving into? What is the state of Mitral valve? (open/closed) What is the state of Aortic valve (open/closed)

Explanation / Answer

8. True.

9. A. Atria are relaxing/systole.

During ventricular diastole, atria are also relaxing so all chambers of heart are relaxing forming joint diastole.

10.

A. During ventricular systole, pressure in left ventricle is higher than pressure in left article.

B. During ventricular systole, pressure is higher in left ventricle than pressure in aorta.

C. Mitral valve is closed during late ventricular systole.

S. Aortic valve is open during late ventricular systole
