    some ions can pass through Tight junctions - Magnesium for example. Tight junctions are not completely impenetrable

    • @magranin7319
      @magranin7319 3 года назад

      Yeah, that’s right! Some are leaky and allow certain ions to pass though but the majority aren’t and so they are known as such.
