1. During the ejection phase of the cardiac cycle, the atrioventricular valves are [ Select ]
["open", "closed"] and the semilunar valves are open/closed?
2. During the ventricular ejection phase of the cardiac cycle, the ventricles are in [ Select ]
["systole", "diastole"] and the atria are in systole/ diastole?
3. What is the net change in pressure in the aorta between the start and end of ventricular diastole
in one cardiac cycle?
Group of answer choices
it increases (gradually, after a sharp decrease)
it increases (sharply)
there is no change between the start and finish point; but it does increase and decrease several
times
it decreases (gradually, after a brief increase)
it increases (gradually)
