2.72 Water reabsorption

2.72 understand that water is reabsorbed into the blood from the collecting duct

Bowman's Capsule - location of ultrafiltration

Dissolved contents of the blood are forced into glomerular filtrate
When filtration occurs - will filter out too much water therefore selective reabsorption occurs

Selective reabsorption of water occurs in the collecting duct:

Filtrate reaches the collecting duct
- Water is removed from the filtrate
- Returned back into the blood vessels
- Back into the bloodstream
- Selected and reabsorbed into the blood
