Stoke volume: the amount of blood ejected during systole The pressure: volume loop (left ventricle) *not in the textbook COPY OUT FROM SLIDES INTO NOTEBOOK! - pressure in mmHg on y axis, volume in mls in x axis -60-30 on x axis in ventricular filling, going from 60 to 130, that’s your 70 mls at that point the mitral valve closes and u start building pressure-vertical line from 130 on x axis straight up, so you know its isovolumic.

I know that during ventricular diastole the cuspid valves are open and the semilunar valves are closed. And during ventricular systole the cuspid valves close and semilunar valves are open. BUT atrial systole and diastole is sooo confusing :S. Please someone explain.

There is now negative pressure in the ventricle (since it is now empty), and this pressure helps to draw in the blood from the atrium when it enters into systole. So during atrial systole (depending on which side we are talking about), the bicuspid/tricuspid valves are open, and the pulmonary/aortic semilunar valves are closed. Then during the diastole part, the bicuspid/tricuspid valves are closed (which makes sense, since we don't want blood from the ventricle getting back into the atrium).

Aortic valves open and 90 on pressure, ventricular ejection, aortic valve closes at 120 on y axis, straight line down from 120 is isovolumic relaxtion, mitral valve open -draw a line from topmost dot to the y axis (you get 120) then get the secondmost top point, and draw over to y axis (get 80) BP=120/80.

When the ventricular pressure exceeds the pressure in the aorta and pulmonary trunk, the semilunar valves are forced open and blood is ejected out. This signals the ejection p … hase of the cardiac cycle of ventricular systole.
