Question : Kidney functioning is regulated by hormonal feedback control mechanism. Explain this mechanism.

Answer»

Solution :1. The functioning of KIDNEYS is efficiently monitored and regulated by hormonal feedback control mechanism involving the hypothalamus, juxta glomerular apparatus and to a certain extent the heart.
2. Osmoreceptors in the hypothalamus are activated by changes in the blood volume, body fluid volume and ionic concentration.
3. When there is excessive loss of fluid from the body or when there is an increase in the blood pressure, the osmoreceptors of the hypothalamus respond by STIMULATING the neurohypophysis to secrete the antidiuretic HORMONE (ADH) or vasopressin (a positive feedback).
4.ADH facilitates reabsorption of water by increasing the number of aquaporins on the cell surface membrane of the distal convoluted tubule and collecting duct.
5.This increase in aquaporins causes the movement of water from the lumen into the INTERSTITIAL cells, THEREBY preventing excess loss of water by diuresis.
