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.
Urination is defined as the process of discharging urine from the urinary bladder, which may involve various characteristics such as frequency, awareness of the act, and the presence of abnormalities like nocturia or dysuria.
