THE KIDNEY ESENTIAL ROLE IN MAINTAING THE ACID BA SE BALANCE OF THE HUMAN BODY
The urinary system is referred as having one of th e most complex and wonderful architectonic structur es in all organic system.Homeostasis is maintained constant d ue to the functional suppleness of kidney.This i s a complex process that requires multiple and complex enzymati c and physicochemical mechanisms.These mechanisms t ake place in the renal interstice,the glomerule or the proxim al or distal tubules.The kidney"s ability is to ma intain a perfect balance between the intake,synthesis and output of stabile acids.In the proximal tubule is happening the resorption of 85% of bicarbonate in adults and the resorption of 65% of bicarbonate in children,from the total quant ity of reabsorbed bicarbonate.In the distal tubule,the rest of 15 35% of the remaining bicarbonate found in the primitiv e urine is reabsorbed. In the urinifer tube the urine has the pH value of 6.2 due to the fact that there are stil l free ions of bicarbonate.This is where H ions are eliminated according to a ionic gradient or reference scale.In chronic kidney failure it is absolutely necessary that we interven e exogenous to try to maintain the body homeostasis .Without these reactions the patients progress will irremediately l ad to exitus.
