HEY UJALA CAN U PLEASE HELP ME IN THIS QUESTION HOW HORMONES ARE INVOLVED IN OSMOREGULATION OF KIDNEYS

Hormones are involved in the osmoregulation of kidneys by regulating the levels of water.

Such as if the water level is excess in the body fluids, the hormone will help the kidneys to filter as much water as they can from the glomerular capillaries. So, As a result dilute urine is formed.

Now, If the water level is very low in the body fluids, the hormone will help the kidneys to absorb most water and filter less water from the glomerular capillaries. As a result the urine formed is concentrated.

In Chapter 3, "Coordination and Control" You will come to know that the hormone is ADH (Anti-diuretic hormone) called vasopressin.

Kidney plays a very important role in Osmoregulation by regulating the amount of water reabsorbed.Anti Diuretic harmone produced by pituitary gland plays a key role.Kidney regulate osmotic pressure of a mammals blood through extensive filtration and purification in a process known as osmoregulation.

The loop of Henle establishes a salt gradient in the medulla, anti diuretic harmine regulates the level of water reabsorption in the collecting duct.

Harmones like ADH helps in reabsorption of water.

Hope this helps...

Good luck on your assignment...
