Osmoregulation Flashcards
1
Q
What is a negative feedback
A
Controlling the water potential of body fluids is an example of a negative feedback mechanism. If the concentration of the blood changes, the amount of ADH released changes to maintain a dynamic equilibrium. Nervous stimulation from the hypothalamus controls the amount ofADH released by the pituitary.

ADH Makes the walls of the collecting duct permeable to water. Water leaves by osmosis and is carried away by capillaries
