Which organ lies posterior to the stomach?

• A. Liver
• B. Kidneys
• C. Pancreas
• D. Spleen

Answer: (C)

The stomach has a direct posterior relationship with the pancreas. The pancreas lies behind the stomach (retroperitoneal), with the stomach’s posterior surface in contact with the pancreas. That makes the pancreas the organ that sits behind the stomach.

The liver is above and generally anterior to the stomach, the spleen sits to the left and beside the stomach rather than directly behind it, and the kidneys are further back and lower, not forming the immediate posterior border of the stomach.
