    You just explained basically 30 pages of reading in my A and P book in a 13 minute video. You are the man.

    My teacher spent like half an hour trying to explain this and failed miserably, but you sir, were successful in less than half the time. You're the man!!

      And some teachers don't care if you understand, they just want to dazzle their students with their intelligence. Thankfully, there are fewer of those these days. AT least I am lucky.

    Hey, Leslie. I'm a senior in college and am in Animal Physiology this semester and it's killing me! Thank you so much for taking the time to post all these videos. They are so helpful!! I just wish I had discovered these earlier and I'd probably have an A and not a B! :)

  • @01rai01
    @01rai01 10 ปีที่แล้ว

    I can confidently say that the reason I ace the pressure-volume curve question on my exam was because of this video. I watched the vid about 4 times and had like Leslie's voice in my head while doing the question.
    Thanks for all you videos.

  • @bams6920

  • @turbotysen
    @turbotysen 9 ปีที่แล้ว +1

    Helped me understand WAY better. My teacher brushed right through this part of the lesson so fast, it was hard for me to retain all of the useful information that I needed. Also just looking it over in the book trying to understand it by yourself is kind of challenging. Much thanks and appreciation!

  • @jessienguyen1193
    @jessienguyen1193 7 ปีที่แล้ว

    Im P1 student, this part of lecture, my professor made it so complicated and confusing. I was struggling w it. I went through couple videos on youtube, but yours are the best. I love the tempo, clear explanation, visual aid you show. Thank you so much!

  • @robertp5615
    @robertp5615 9 ปีที่แล้ว +12

    Great video! thanks for the explanation. One thing though, the 4th sound has to do with the active filling of the ventricle (due to atrial contraction), not the filling of the atrium. Just like the 3rd is the passive filling of the ventricle, the 4th is the active. Thank you again for the great video!

    Thank you SO MUCH for these videos, I have a particularly inconsistent and confusing teacher for physiology who is unable to organize the material in a way that makes sense and is cohesive. I wish I could have paid you the tuition instead as these videos are how I am really learning. I wish all teachers could teach the way you do. you are amazing! Truly, from the bottom of my heart, thank you!

  • @annetteasbury7415
    @annetteasbury7415 10 ปีที่แล้ว

    Thank you so very much for this video sir! We had this same diagram presented to us in our NP advanced pathophysiology/physiology course and the instructor just blew through it as if it was something we had been previously exposed to. The only thing that was clear was that it supposedly represented the cardiac cycle. Thanks to your video I can now go back to the diagram and actually UNDERSTAND what's going on. Thank you so very much!

  • @thegarbageman21
    @thegarbageman21 11 ปีที่แล้ว

    Yes you are correct. The ventricle AV valves are open and at ventricular low pressure (after relaxation) so the blood will pour in from the atria. Remember you have all that blood coming into the atria from the Vena Cava which makes atria have more pressure than vent. In young people ventricles actually get over 80% of the blood before the atria contract. When you get older however the ventricles get stiffer so that atrial pumping mechanism becomes more important to squeeze that blood in.
