Describe the negative feedback loop that stimulates thirst as a result of dehydration
What will be an ideal response
Dehydration causes 1 ) decreased flow of saliva, which dries the mouth and pharynx, 2 ) increased blood osmotic pressure, which stimulates osmoreceptors in the hypothalamus, and 3 ) decreased blood volume, which lowers blood pressure, increasing release of renin from JG cells, increasing levels of angiotensin II. All of these stimulate the thirst center in the hypothalamus, which increases fluid intake via thirst, thus increasing body water.
