    everyone is med school, at some point, tests their understanding of the material or hears the voice of their professors in their brain even when they're sleeping cause they've studies 12-14 hours straight, I had that happen to me with Ninja nerd videos & Zach's voice & Anki makes me test my understanding even in sleep/ light sleep. Zach- you're the best at explaining things to a level that they actually make sense & you follow through with every concept and it's collateral context in it's entirety, which most professors fail at. I cannot thank you enough, for helping me detangle the jumbled neuronal circuitry for so much of the material that professors & textbooks only rally jumble further. So Zach + boards & Beyond + pathoma + Drawittoknowit + silver thorn textbook + some Anki are so much of my life lately. (I wish professors lecture notes sufficed, but they just simply don't even though my school had some really stellar profs. I am obsessive I have to understand things logically, so I don't have to do explicit memorization.

    You explained this concept better than my medical school professors can. It's shocking that you covered more clinical correlates on this topic than we were given.

  • @laurapeterson559

    This was...beautiful. I've had 3 different professors try to explain this material, and I got the basics but nowhere near a solid understanding. And you fixed it! You put it into English, and I get it now! I can't wait to tell my study group! And my professor!!!! Thank you! Big test tomorrow, and I'm no longer worried!!

  • @ayushpatel-eu2xt
    @ayushpatel-eu2xt 3 роки тому

    Zach i think the osmotic pressure on the venule side of the capillary must be higher because we lost water making the blood plasma more concentrated so the osmolarity increases. Therefore i think we should be having a higher osmotic pressure on the venule side of the capillary. i might be wrong though u can correct me.

  • @waraqasim8267
    @waraqasim8267 5 років тому +10

    Thank you so much for this explanation. But Kindly answer one question of mine from this video
    You said that when MAP goes up, vasoconstriction occurs to to reduce blood flow. In your videos related to blood pressure, you said that b.p goes up when vasoconstriction occurs bcz of increased resistance. Is there a difference between MAP and b.p?
    PLEASE PLEASE SORT OUT MY CONFUSION. I WILL FOREVER BE GRATEFUL.
    BEST REGARDS

    • @swagnikdas524
      @swagnikdas524 4 роки тому

      He said in his blood pressure videos that BP = MAP-CVP where MAP= Mean Arterial Pressure
      CVP= Central Venous Pressure
      Since CVP is very less we neglect it so it can be said MAP is appropriately equal to BP

    Please don't take this the wrong way, you still explained this topic better than my med school professors, however for constructive criticism i felt that this video was one of the harder ones to follow. I think because you jumped all over the board. Anyways still thank you, and cant wait for your website launch and will absolutely get myself some ninja nerd merch!

  • @hasifhamid1909

    hi, can i ask a question, why does arterial vasoconstriction causes an decrease in hydrostatic pressure ?

    • @roaaalqadoor8683
      @roaaalqadoor8683 17 днів тому

      Arterial vasoconstriction causes the velocity of blood to increase, subsequently increasing the kinetic/mechanical energy. According to the law of energy conservation, potential energy carried by the blood is decreased when an increase in kinetic energy takes place. Decreasing potential energy =>decrease in hydrostatic pressure (since hydrostatic pressure of force exerted by blood on arterial walls)
      Hope that answered your question!

    That a low MAP responds with vasodilation and a high MAP responds with vasoconstriction seems backwards to me. Please help me understand. I LOVE your videos.
