the homeostatical function of kidney is to regulate the concentration of water and salts in the body through osmoregulation.
Yes it is since when one excretes, the kidney releases excess water from the excretory system hence osmoregulation takes place.
Kidney
It is urine's specific gravity that measures the kidney's ability to concentrate or dilute urine in relation to plasma.
A low GSR ( glutathione reductase) in relation to kidney function indicates that an infection is possible. Low levels of GSR can indicate pseudomonas and staph infections.

The main organ in the excretory system is the kidney. The kidney is the main organ that controls the excretory systems for vertebrates. It is also part of the Urinary system which is part of the excretory system.
I hope this helps :) Osmoregulation is the process by which body fluids are maintained at a constant level. In the kidney there are the Bowman's Capsule and also the loop of Henle which reabsorbs and filters the excess water, salt and urea. In the brain there are the hypothalamus and pituitary gland that controls the process of osmoregulation. The hypothalamus detects the changes in H2O level while the gland secretes Antidiuretic Hormone (ADH) into the blood stream. ADH is produced when H2O levels are low. This causes the loop of Henle and distilled convoluted tubule to reabsorb more H2O. The production of ADH stops when normal conditions are restored. When there is too much water the kidney will remove it and urine will become more dilute
The kidneys are organs that serve several essential regulatory roles in most animals, including vertebrates and some invertebrates.
In the urinary system, osmoregulation takes place in the renal tubules and collecting ducts in the kidney. These parts are where selective reabsorption takes place, where water, glucose, salts and other necessary substances are absorbed back into the surrounding blood capillaries, from the renal tubule, which eventually leads to the bladder. The tubule is affected by the hormone ADH (anti-diuretic hormone) from the pituitary gland in the brain, which makes the renal tubule membrane more permeable, so more water can be reabsorbed, or vice versa - Makes the membrane more permeable so that more water is excreted. Osmoregulation is an example of homeostasis.
They are primarily responsible for filtering blood by removing nitrogenous wastes, though they also regulate blood pressure in a process called http://www.answers.com/topic/osmoregulation and also assist with the production of red blood cells.
