Antidiuretic hormone (ADH) is important in maintaining homeostasis in mammals. ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries. The amount of hormone released is controlled by a negative feedback loop. Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production?

ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries.

Explanation

. This option is the mechanisms of regulation of osmoregulatory balance in urine production by the kidney

ADH responds to high solute potential of the blood(high osmolarity) by stimulating the opening of transmembrane proteins AQUAPORINS in the walls of the distal and collecting tubules

This promotes influx of Solutes from the passing tubules into the peritubular capillaries.Water follows by osmosis(reabsorption),untill the osmolarity of these fluids drops.

As this occurs the hypothalamus stopped the production of ADH, the aquaporins closes up,solute influx into peritubular capillaries stoped and therefore water influx

This is negative feedback Mechanism.it is an example of homeostatic process of maintaining water balance of the body during urine formation .
