Urinate

v. discharge urine from the body, discharge fluid excrement from the body

Urination, known by physiologists as micturition, or more simply as voiding, is the process of disposing urine from the urinary bladder through the urethra to the outside of the body. In healthy adults, the process of urination is under voluntary control; in infants and individuals with neurological injury, urination may occur as an involuntary reflex.
