Document Summary
Lecture 13 - cardiovascular physiology (part 7 of 9) (1) right heart (2) starling s law of the heart (frank-starling mechanism) Wiggers diagram was all for left side of heart. The exact same thing is happening on right side of heart. First of all everything is on the right and second, instead of seeing big pressures going up 120mmhg it goes up to maybe about. 20mmhg because pressures on right are less than pressures on left. Everything is happening a the same time though. You have the same four cycles of the cardiac cycle. If we could increase this more, when you stretch cardiac muscle it contracts more forcefully so if you increase the edv, you ll get a more forceful contraction and you ll eject more blood (higher stroke volume). You get this curve by doing a bunch of edv.
