    Hello, I normally do not comment on anything really but i just would like to say you are a great teacher! your videos have helped me understand so much. I currently have one of the worst A&P II teachers in history and your videos have helped TREMENDOUSLY. Thank you!!!

    There are two major types of resistance: 1. Systemic or peripheral resistance (synonyms) 2. Pulmonary resistance.
    When I say "total body resistance" I mean #1 (Systemic or peripheral resistance). I hope that helps! =)

    Hey!,
    I think your videos are awesome! BUTT.......I think you can make them even better :)
    In this video you spoke about about pressure, flow and resistance,
    when I come back to watch these videos (around exam time) and lets say I want to learn about resistance, having info about what time each topic starts would help! :). Kinda like a playlist-specificing when new song starts and ends

    I have always known the equation delta P=Q X R as Change in BP=CO X PR. Are these equations the same? the later is less common nowadays. They sound the same though the later seems very simple to relate to change in BP or to conditions that alter CO or PR. Good job khan.

    • @StrongMed
      @StrongMed 10 ปีที่แล้ว +3

      Sort of the same. delta P = Q x R is the same as: MAP - CVP = CO x SVR. (MAP = mean arterial pressure, CVP = central venous pressure, and SVR = systemic vascular resistance). Since usually, CVP

    change in pressure is the same as mean arterial pressure?

  • @Dr0xyg3n
    @Dr0xyg3n 5 ปีที่แล้ว +1

    I just do not agree on that blood pressure. Because some medics say that 90 is the optimal blood pressure. But it's not the normal blood pressure of the human body. I have never seen a patient with a blood pressure of 90 that was not about to faint (if it wasn't a underweight, small girl)

    • @RocktracksSC
      @RocktracksSC 7 ปีที่แล้ว +1

      I'm pretty sure its an increase in to total cross-sectional area in the capillaries that cause the pressure to drop as blood gets there

    Umm, I feel like some of this denies the established laws of fluid dynamics. Fluid dynamics tells us that when fluids enter a pipe that changes in size, the velocity changes but the pressure should remain the same. This I am confused by your changing pressures as blood moves throughout the body.

    Bless the person/people that add Bulgarian subtitles to all the Khan videos about blood pressure (and even more videos that I've seen with Bulgarian subtitles!) I understand English pretty well, but when you're learning a subject with new terms it's nice to know what it's called in your native language too. Thank you so much!
    And also, let's not forget to thank Mr. Desai at Khan Academy for helping us understand all of these concepts!
