2.72 Water Re-absorption



Notes


**Bowman's capsule = ultrafiltration ---> dissolved contents of plasma forced to become glomerula filtrate (water/salts/urea/glucose)

Filtration ---> filters out 'too much water' (as filtrate passes through nephron structure and reaches collecting duct)
---> Passing through collecting duct = water removed from filtrate (returned back to blood vessels/blood stream)
----> Water reselected to be reabsorbed into blood stream = 'selected reabsorption of water' occurs in collecting duct
