Reabsorption of Water
Reabsorption of water & salts
- As the filtrate drips through the Loop of Henle necessary salts are reabsorbed back into the blood by diffusion and active transport
- As salts are reabsorbed back into the blood, water follows by osmosis
- Water is also reabsorbed from the collecting duct in different amounts depending on how much water the body needs at that time
