Urine is the result of the excretory system balancing the amount of water and salts in your body. We said the system is small. Your kidneys are the core organs involved in the excretory system.
Urine leaves the medullary collecting ducts through the renal papilla, emptying into the renal calyces, the renal pelvis, and finally into the bladder via the ureter.
While urine and feces are both waste material of body processes, they are in completely different categories. Urine is a waste product of the urinary system process while feces are waste products of the digestive system.
Although urine formation occurs primarily by the filtration-reabsorption mechanism described above, an auxiliary mechanism, called tubular secretion, is also involved.

dRTA (distal renal tubular acidosis) results from the failure of the a-intercalated cells in the distal tubule of the nephron to acidify the urine.
If there is blood in your urine, you know you have a problem. The tubule cells of the nephron then process this filtrate to form urine (excretion). This is done by a selective process involving active transport and the utilization of a lot of ATP.

Another enzyme called TPMT (thiopurine methyltransferase) plays an important role in the chemotherapy treatment of a common childhood leukemia by breaking down a class of therapeutic compounds called thiopurines.
