Final answer:
The term 'urinary meatus' does not refer to the act of urination but to the external opening of the urethra.
Step-by-step explanation:
The term that does not refer to the passage of urine from the body or the emptying of the bladder is urinary meatus. Urinary meatus refers to the external opening of the urethra, through which urine exits the body. The other terms provided refer to the act of urination in various ways: urination and voiding are common terms used for the release of urine from the bladder, and micturition is a less common medical term that describes the same process.
