When the pressure inside the ventricle causes the atrioventricular valve to close and the semilunar valve to open, which statement about the heart is true?

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

c. The amount of blood in the ventricles at the end of the ventricular filling phase is the end-systolic volume.

Mr. Watson has been diagnosed with mitral insufficiency, or a malfunctioning mitral valve, which causes the valve to not close properly. Predict the signs and symptoms you might expect from a disease of this valve. What would happen to the patient's stroke volume and cardiac output? Explain. What might help improve his cardiac output?

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

c. Tissue perfusion to the heart decreases during systole and increases during diastole.

For the atrioventricular valves to be open, the pressure in the ventricles must be:

What event immediately follows the closure of the atrioventricular valves and coincides with the onset of ventricular systole?

During which following phase (or phases) of the cardiac cycle is the blood volume in the ventricles constant?

If the pressure in the ventricles is higher than in the atria, which of the following statements must be true?

I. The atrioventricular valves are closed.

II. The semilunar valves are open. 

III. The ventricles are in systole.
