POINT!
| With sweating/water intake, the (blue→red/red→blue) negative feedback increases/decreases the number of water channels. |
Challenge Quiz
1.
Sweating Water intake increases plasma osmolarity, and water reabsorption (through the water channels) increases decreases plasma osmolarity. Since these effects are in the same opposite direction, negative feedback increases decreases the number of water channels.
