MCB 247 Final Physiology Review
Spring 2012
![Page 2: MCB 247 Final Physiology Review](https://reader030.vdocuments.net/reader030/viewer/2022033105/56816570550346895dd80446/html5/thumbnails/2.jpg)
1. What phase of the cardiac cycle is displayed in this picture?
A. Ventricular systole- first phase: Ventricular contraction pushes AV valves closed but doesn’t create enough pressure to open semilunar valves.
B. Ventricular diastole- early: As ventricles relax; pressure in ventricles drops; blood flows back against cusps of semilunar valves and forces them closed. Blood flows into the relaxed atria.
C. Ventricular systole- second phase: As ventricular pressure rises and exceeds pressure in the arteries, the semilunar valves open and blood is ejected.
D. Ventricular diastole- late: All chambers are relaxed. Ventricles fill passively.
