What is the function of the urethra?

• A. Eliminates urine from the body.
• B. Reabsorbs water.
• C. Produces hormones.
• D. Pumps urine into the kidneys.

Answer: (A)

The urethra serves as the final exit pathway for urine. After urine is produced in the kidneys and stored in the bladder, the urethra carries it from the bladder to the outside of the body, with muscle sphincters helping control when urination occurs. This makes it the structure responsible for eliminating urine from the body. Reabsorption of water happens earlier in the kidney tubules, where filtrate is processed to reclaim water and other substances. Hormone production occurs in the kidneys and other organs, not in the urethra. Pumping urine into the kidneys would require moving urine upward the tract, which is not how urine flow works.
