==The Kidney==

The kidneys are paired organs which reside in the dorsal abdomen.  One on the left and one on the right.  Their role is to filter the blood throught the glomerulus to form what is known as the filtrate.  This filtrate is then on the whole reabsorbed along the nephron until what is left comprises of compounds superflous to the requirement of the organism.  Some compounds, normally fully reabsorbed, are on occasions present in the body in excess.  The kidney tubules are able to respond to this excess and excrete such compounds in greater amounts.  This is how the kidneys play a major role in the homeostasis of the organism.  The kidneys also play a vital role in the total water balance of the organism.  Varying their excretion of water in relation to the hydration state of the animal.
