      Ganong review...Renal chapter.

    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.)

  • @usum9325
    @usum9325 2 года назад

    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 года назад

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

  • @ronihelor2555

    Why in 1:33 you say osm/volume is osmolality
    Though osmolality is osm/kg

  • @Achilleeeez
    @Achilleeeez 3 года назад

    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?

  • @ahmedelfadil1270
    @ahmedelfadil1270 3 года назад

    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 года назад

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

    WOULD MEAN A LOT IF YOU REPLY HEHE

      A substance that can pull water towards it across a semi-permeable membrane.

  • @shahdmohamed5998

    Thank you so much but I just have a question the Na+ passes through the channels of the plasma membrane as it is a small ion passing with water and also durnig the active transport through the Na, K pump so how it is an effective osmole?

  • @amidmd
    @amidmd Год назад

    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  Год назад

      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.

  • @user-vn8ro9iz5x
    @user-vn8ro9iz5x 4 года назад +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?
