Cardiovascular | Cardiac Cycle: Digital Version

Official Ninja Nerd Website: ninjanerd.org
Ninja Nerds,
Join us for our lecture where Zach will teach you all of the information you need to know to understand the cardiac cycle. During this lecture you will learn how the heart functions during the cardiac cycle which will include mid-late ventricular diastole, isovolumetric contraction, mid-late ventricular systole, and isovolumetric relaxation. We hope you enjoy this lecture and be sure to check out all of our social media pages and ways to support us below!

It's a good new method... but I prefer the Whiteboard and the Ninja Nerd in front of it. :( It was easier to understand, when you show with your hands what you mean.. please come back to the screen!

[@mohammadghazzawi7565]

you are an amazing and the best teacher I have been seen from the middle east big thank you

[@divapradana1056]

The best teacher But i like when u use the whiteboard :(

[@georgepaul6240]

Amazing as always but I miss u drawing

[@fernandaverduga1565]

totally

[@user-vw5pl8lj9p]

This format is amazing!! I watched the older video on cardiac cycle when you drew everything out on the whiteboard and that was very helpful. But now that I'm able to compare all 4 at the same time in such an organized manner... thank you so much, you guys are seriously amazing.

[@NinjaNerdOfficial]

We are so happy you liked it! We just want to continually keep growing to help our Ninja Nerds out in a variety of ways!

Is this illustration for members only? Can’t we download it if we don’t pay?

[@kyla1602]

You know your tutorials are amazing when so many people watch both that cover the exact same material. HAHA. I do love the whiteboard, but this is was also a great supplementary video as it organized the material better. The whiteboard was helpful to fully understand what was happening as we watched you draw it out... and this was a great review of that material to really hit it home. I'm 2 years late to the party on this video, but its still amazing.

[@NinjaNerdOfficial]

No, you just found the video when you needed it! Welcome to the Ninja Nerd community!

Great video but I wish you guys taught on the white board it was much easier to follow :(

[@kurikong2379]

I couldn't understand this while reading Guyton and Hall, I almost cried bcos I thought I was stupid and it sound so complex. But it made total sense after I watch this video. You amazed me as always, Ninja nerd! Thank you

[@wolfie5470]

@@NinjaNerdOfficial Happy to hear that :D But I know that there is a HUGE work behind all the stuff you do :) And I know that this technique allows you to do all the things even better and even easier to understand (if it is even possible). I also forgot to say that its amazing idea to make the template so we can write it with you and have a paper to take with us anywhere we want. When i tried to draw all the stuff like you it usually really didnt look as nice as yours :D This is def gonna save our time. I really appreciate all the hard work you all do for us. ♡♡♡

You are amazing and saving my degree !!!! ❤😊 Would it maybe be possible to get an "Screenshot/Freeze" time overview from all the Whiteboard/Presentation in the videos in the end as well? Like it was possible in this one? That would be so great! 🎉 GO Ninja Nerd :D😊

[@PRISCILLABURLISON]

I like the new format, just Joined, little pricey for a student, but i need to pass! Question: during Isometric Relaxation, isnt it P ventricular < P arterial, atleast thats what my professor is saying. B/c no change in volume, no blood moving & ALL valves are closed. Please clarify, thanks in advance.

[@muhammadnabil3390]

I'm super duper late to the party but i'll really appreciate if some one can explain to me a problem i'm having to understand. During mid to late ventricular systolic phase/ ejection phase,when the pressure is greater inside the ventricles as compared to either atrial or arterial then why doesn't the tricuspid & mitral valves open up but only the pulmonic & aortic semi lunar valves open up...? I know the atrio-ventricular(tricuspid & mitral valves) valves will not allow the backward flow of blood from ventricles to atria but still,if the pressure is high in the ventricles & this same high pressure can force the semi lunar valves to open & spill the blood into pulmonary trunk & aorta then why not force the atrio-ventricular valves to also open up...? P.S. Sorry for the lengthy statement.

[@Tpry]

S1 is the closure of the Mitral and Tricuspid valves. The ventricular pressures greater than atrial pressures close the AV valves . This is early systole or early QRS ( isovolumetric contraction - before blood rejects from the ventricles.. S2 is the closure of the Aortic and pulmonic valves, after the blood has ejected out of the ventricles. The Aortic and Pulmonic pressures are greater than Ventricular pressures - close the valves. This is the T wave repolarization of Atrium. or Isovolumtetic relaxation.

[@kuyashasarkar8328]

In places where there is no gravity, like in the ISS, how does the passive flow of blood from atria to ventricle occur? Does it affect the stroke volume?

[@archijyotirmayeevishwanidh2767]

Sir you have described The ventricular pressures during different parts of the cycle differently in both your videos. Esp pressures described during the Isovolumetric contraction. which one is correct?

[@archijyotirmayeevishwanidh2767]

there is a very faint S4 sound due to blood hitting the ventricular walls durnig Atrial systole/ Mid to late ventricular Diastole. is that pathological too? if you can hear it?

I am glad you posted this. I did not realize that the s1 and s2 sounds had both sets of valves closed, even though s1 is av valves snapping and s2 is semolina valves closing

[@michelleaugustinas8316]

I should rephrase. The isovolumetric phases have all 4 valves close, but since they happen so close to one another, it is often described as one set of valves being opened while the other set is closed.
