What term describes the act of discharge or draining urine?

The term that describes the act of discharging or draining urine is "voiding." This term is specifically used in medical and healthcare settings to refer to the emptying of the bladder, which is a crucial bodily function. Voiding can encompass both the act itself and the physiological process behind it.

While "urination" is often used synonymously with voiding, it may not encompass the full scope of the term as it traditionally refers to the process of producing urine in the kidneys and expelling it from the body. "Flushing" typically refers to rinsing out or cleaning, particularly in relation to toilets or medical procedures, and does not accurately describe the act of releasing urine. "Excretion," on the other hand, refers more broadly to the elimination of waste products from the body, which includes but is not limited to urine. In this context, voiding is the most precise term to describe the specific act of draining urine.
