Which of the following organs is NOT part of the genitourinary system?

The pancreas is not part of the genitourinary system; it is an organ that plays a critical role in the digestive and endocrine systems. Specifically, the pancreas produces enzymes that aid in digestion and hormones such as insulin, which regulates blood sugar levels.

In contrast, the kidneys, ureters, and urethra are all integral components of the genitourinary system, which is primarily responsible for the production, transport, and elimination of urine. The kidneys filter blood to produce urine, the ureters carry urine from the kidneys to the bladder, and the urethra is the tube through which urine is expelled from the body. Understanding the distinct functions and roles of these organs clarifies why the pancreas does not belong to this system.
