    great video! really helped! Just a suggestion, do leave the diagrams on when your talking as it would be better to register the information whilst looking at a diagram. Thanks

      Ah ok - you’re doing double award. Then no, this definitely won’t come up. Paper 1BR is a regional paper for students in China/HK/UAE and some other countries. Everyone else sits 1B

    Where is the pressure that causes ultrafiltration? Is it in the Efferent arterial 'cause it's got a smaller lumen? or is it in the capillaries? Thanks! Your videos have been really helpful!

    • @linasaadani636
      @linasaadani636 5 років тому

      I think so; I learnt that it was because the efferent arteriole was smaller than the afferent, so you're probably right :)

    i needed to know about why desert animals have longer loopes of henle, can you explain that?

    • @faustoleto5441
      @faustoleto5441 7 років тому +5

      The longer the loop of henle the more water is reabsorbed, desert animals have longer loops of henle as they live in an arid environment and need to conserve more water.

    Do you need to know about the nephrons and stuff for AQA because neither my teacher nor the CGP textbook mentions it?
    (Great video by the way very helpful)

    • @SciencewithHazel
      @SciencewithHazel  6 років тому

      If you're doing AQA separate science then you need to know the function of the kidney, the process of filtration and selective reabsorption to produce urine, and the effects of ADH. You don't need to know about the actual structure of the kidney or the nephron though.
