  • Osmolality, Osmolarity, and Tonicity.
    Osmosis is a special type of simple diffusion (specifically for water). Osmosis is the movement of water from high concentration of water (low concentration of solute) into low concentration of water (high concentration of solute).

    I have a question please ,i m preparing my exam about renal physiology ,i m searching for questions MCQ about that item ,can you give me a website for Free to evaluate myself . keep going your nice work.

    If you heat 100 mLs of water the volume (osmolarity) will expand but the weight (osmolality) will not. The lightbulb just went on! 💡 (PS: After university, I lived in Edinburgh -- love Scotland, my ancestral homeland.)

    Very nice video :) I have just one question i not really get. In the nephron we have urea transporters (for example in the end of the collecting duct). For transport of urea back in the system right?
    And how we get an urea concentration in the nephron when its always moves through cells?

    • @MedicosisPerfectionalis
      @MedicosisPerfectionalis  Рік тому

      Urea back-diffusion occurs from the nephron (tubule) to the renal medullary interstitium…This urea will help pull water out of the tubules making the urine more concentrated.

  • @Achilleeeez

    In the slide at minute 1:26, it says both that Osmolality is per volume (l) and per mass (kg). Wrong? Because the first is the definition of osmolarity, right?

  • @tamilspeaker2507

  • @usum9325
    @usum9325 2 роки тому

    Is it osmolality or tonicity that affects the secretion of ADH? It is usually said that ADH is secreted by high osmolality, but it is confusing because Urea does not affect the secretion of ADH.

    • @MedicosisPerfectionalis
      @MedicosisPerfectionalis  2 роки тому

      If I have high serum osmolality, it means that my serum is hypertonic, so both are correct!

    In this minute 4:17 you said that osm. Of IS =osm. of plasma= osm. Of ICF
    But IS +plasma =ECF
    And ECF osm.should equal ICF osm. How is this correct ?

    • @MedicosisPerfectionalis
      @MedicosisPerfectionalis  3 роки тому

      You’re confusing volume with osmolality.
      ECF volume = ISF volume + plasma volume.
      However, all of them have equal osmolality.

    Though osmolality is osm/kg

  • @user-vn8ro9iz5x
    @user-vn8ro9iz5x 4 роки тому +3

    Why can’t molarity be used instead of osmolarity? I understand that osmolarity calculates the number of particles instead of molecules but I’m still not quite sure why can’t we use molarity?
