Urine is formed in the kidneys, specifically by the renal tubules in the nephrons of the kidneys. It then is collected by the renal pelvis, where it exits though the ureters, moves to the bladder where it is stored until urination, during which it is expelled through the urethra.
When the body becomes too acid, the kidneys remove more acid into the urine. If the potassium levels get too high, the kidneys remove more potassium into the urine. Urine is formed in the nephrons in three process: glomerlular filtration, tubular reabsorbtion and tubular secretion. The amount of urine varies based on fluid intake and climate.
