  1. HI!! I’m french but I can understand english, and I’m so lucky I can,
    because those videos are awesome !!! I can never find good explanations for
    my medicine school things. That’s absolutely amazing that you give your
    time to spread knowledges ! uninteresting boring things become so
    fascinating !

  2. EUREKA…HE TEACHES MORE MEDICINE THAN THE PALE AND FRAIL OF US MEDICAL
    SCHOOLS!!! LMFAO

  3. I have a question.. I thought sodium is taken in for exchange of potassium.
    Would the osmoles in the blood be very much affected?

  4. go to the khanacademy website and run through the playlist! It has an order
    made for viewing.

  5. Great job :)

  6. I’m learning the urinary system right now in A&P and I love these videos!!!
    I’m trying to find the correct order to watch them though… any
    recommendations?

  7. you are not knan.. i dont believe you

  8. Would you say that if you increase the blood concentrations of aldosterone,
    less ADH will be released?

  9. One question, it may be a bit off topic: When we look at the medullary
    concentration gradient of the kidney and role the vasa recta play in
    maintaining that concentration, why does the vasa recta plasma leave
    slightly hypertonic when leaving the medulla. I know the speed of blood
    flow doesnt allow proper equilibrium to be acheived…but what significance
    it the hypertonic plasma. Is it that the more hypertonic plasma will allow
    increase water reabsorption in other parts of the body…confused

  10. you have a good way of teaching, I am just wondering what did you get on
    the MCAT

  11. More Aldosterone would help retain sodium and water (in equal parts) so
    this should not change osmolarity which is the main thing that affects ADH
    levels.
