Which of the Following Organs is Described as Retroperitoneal

Question

Which of the following organs is described as retroperitoneal?
A) stomach
B) kidney
C) urinary bladder
D) large intestine
E) spleen

Accepted Answer

The kidneys are retroperitoneal, which means they are located behind the peritoneum (the lining of the abdominal cavity) and not within the peritoneal cavity itself. The other organs listed are not retroperitoneal; the stomach, large intestine, and spleen are all within the peritoneal cavity, while the urinary bladder is located within the pelvic cavity.
