During urination, the urine is passed from the bladder through the urethra to the outside of the body. 800â2,000 milliliters (mL) of urine are normally produced every day in a healthy human.ollowing filtration of blood and further processing, wastes (in the form of urine) exit the kidney via the ureters, tubes made of smooth muscle fibers that propel urine towards the urinary bladder, where it is stored and subsequently expelled from the body by urination (voiding).
