Question

ADH is a hormone produced in the _____Angiotensin controls the release of this hormone from the ____ Once released ADH allows aquaporins to fuse to the plasma membrane collecting duct thus increasing the reabsorption of water by the kidney

Answer 1

ADH, produced in the hypothalamus and released from the posterior pituitary gland, regulates water reabsorption in the kidneys by causing aquaporins to be inserted into the plasma membrane of collecting duct cells, thereby conserving water in the body.

Step-by-step explanation:

The hormone known as antidiuretic hormone (ADH), also referred to as vasopressin, is produced in the hypothalamus and stored in the posterior pituitary gland for later release. It plays a crucial role in regulating the body's water balance.

ADH is triggered by osmoreceptors in the hypothalamus that detect an increase in the osmolarity of blood plasma. This leads to its release into the bloodstream. Once it reaches the kidneys, ADH facilitates the reabsorption of water by causing aquaporins to be inserted into the plasma membrane of the cells in the collecting duct. This increases the permeability of the ducts to water, leading to more water being reabsorbed into the capillaries and less being excreted as urine, thereby conserving water in the body.

Alterations in the osmolarity of blood plasma are closely monitored by the hypothalamus, which adjusts the release of ADH accordingly. This process is part of a sophisticated feedback mechanism that helps maintain homeostasis in the body's fluids.
