|
blood enters the coronary arteries |
||
|
the pulmonary semilunar valve opens |
||
|
the left atrioventricular valve closes |
||

Homework Answers
During the contraction of left ventricle, the aortic semilunar valve gets opened and the oxygenated blood gets ejected into aorta. Hence the following that does not occur during contraction of left ventricle of a normal heart are:
- Blood enters the coronary arteries
- The pulmonary semilunar valve opens

1. In the left ventricle, why does isovolumetric (isometric) contraction occur during the first phase of ventricular systole? A. The bicuspid valve needs time to sit before the ventricle can eject blood. B. Ventricular pressure is greater than atrial pressure so the ventricle cannot eject blood. C. The ventricle is still filling with blood and therefore cannot eject blood during this time. D. Aortic pressure is higher than ventricular pressure and the ventricle must pressurize the blood to open the...

2. Aortic valve stenosis is a hardening of the aortic valve which makes it difficult to eject blood from the left ventricle. What effect does this have on the normal electrical and/or pressure events of the cardiac cycle? In your answer, you should include terms and processes such as right atrium, tricuspid valve,right ventricle, pulmonary valve, pulmonary circulation, left atrium, bicuspid valve, left ventricle, aortic valve, systemic circulation, systole, diastole, ventricular systole/diastole, atrial systole/diastole, passive ventricular filling, “atrial kick,” isovolumic...
