  • This video covers:
    - The 3 main functions of the kidneys:
    1) removing waste,
    2) regulating levels of ions, and
    3) regulating levels of water
    - How the kidneys can achieve all of this using filtration and selective reabsorption
    - How anti-diuretic hormone (ADH) is used to control water levels
    Exam board specific info:
    AQA - Separate science only. The ADH part is higher tier only.
    IGCSE - Separate science only
    Edexcel - Separate science only. The ADH part is higher tier only.

    hi i want to know if kidney has already absorbed glucose (during the first stage ultrafiltration) why would it reabsorb glucose again (during selective reabsorbption stage)

    • @strangersinbedband9986
      @strangersinbedband9986 3 ปีที่แล้ว +1

      the kidneys have a filter, and as glucose is fairly small in size it passes through the filter, where blood cells and proteins do not. But as the body needs the glucose, it is selectively reabsorbed. It's not a perfect system, basically the kidneys don't really want to absorb the glucose but because its so small it passes through the filter along with the mineral ions, urea, etc.
