Which system produces, stores and eliminates urine, including kidneys, ureters, urethra, bladder and prostate gland?

• A. Nervous System
• B. Musculoskeletal System
• C. Female Reproductive System
• D. Urinary System

Answer: (D)

The urinary system is responsible for producing, storing, and eliminating urine. The kidneys filter blood to make urine, the ureters carry that urine to the bladder for storage, and the urethra is the passage through which urine exits the body. While the prostate gland sits around the urethra in men and can influence urine flow, it is not a primary part of urine production or elimination. Given the listed organs, the system that best fits these functions is the urinary system. The nervous or musculoskeletal systems don’t produce or regulate urine, and the female reproductive system isn’t involved in urine production or elimination, so they’re not appropriate choices.
