This is one of the best videos I've ever seen in my life. Shout out to evolution for creating this marvelous organ that is the heart!

[@zchat35]

The best and most concise explanation of the pressure-volume loop of a cardiac cycle I have ever listened to in 25 years of my medical career! Thank you 😊👏👏

Wow! Thank you! 🙌🏼 💕 ✨

Did atria passes only 70ml blood to ventricle as 50 ml blood is already present as ESV???

[@nickson7603]

It's not a perfect 70 ml. It may be somewhere between 30 to 70 depending upon the heart rate👍

[@أباذرهشام]

Brilliant 🎉❤

Thank you! 🥰

[@kanishkagarg1391]

At 3:05 semilunar valves is closed not av valves

[@hello6303]

She wrote AV as Aortic Valve(SL valve in other word), not atrioventricular valve. Got kinda tricked too lmao 😅

Thanks, Kristine! 💖

[@texastexas4541]

Please answer this question. I think all textbooks show it wrong. SV increases as EDV increases and they all shorten to the same ES point on the ESPVR curve. Why should it shorten to the same end systolic pressure or point? If you increase SL (as in higher EDV) you should get more force (Force-length relationship) and more force means higher pressure. If they all shortened to the same ESP when you increase EDV, how would they even get the ESPVR curve?

[@Hs-mh1km]

It would be better if you consult your professor regarding this.
