The process of eliminating urine from the body is called

• A. Urination
• B. Filtration
• C. Secretion
• D. Absorption

Answer: (A)

Urination is the act of removing urine from the body. It happens when the bladder empties after detrusor muscle contraction and sphincter relaxation, allowing urine to exit through the urethra. This is the final step of the urinary process, following formation in the kidneys.

Filtration, secretion, and absorption describe how urine is formed: filtration moves fluid from blood into the nephron; secretion adds substances into the filtrate; absorption reclaims water and solutes back into the blood. These are processes that create and modify urine, not the act of eliminating it from the body.
