Which structures comprise the urinary system?

• A. 2 kidneys, 2 ureters, bladder, and urethra
• B. Heart, liver, and spleen
• C. Lungs and heart
• D. Stomach and intestines

Answer: (A)

The urinary system is made up of the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood and help regulate fluids and electrolytes, forming urine. That urine travels through the ureters to the bladder, where it is stored until it’s expelled via the urethra. The other organ groups belong to different body systems: the heart, liver, and spleen are not part of urine production; the lungs and heart relate to breathing and circulation; and the stomach and intestines handle digestion. So, the option listing the kidneys, ureters, bladder, and urethra correctly identifies the urinary system.
