the superior portion of the abdominopelvic cavity which contains the following organs: stomach, small intestine, part of the large intestine, liver, gall bladder, spleen, pancreas, kidneys, and the adrenal glands.

• A. Abdominal cavity
• B. Abdominopelvic cavity
• C. Pelvic cavity
• D. Thoracic cavity

Answer: (A)

This tests how the abdomen is divided into regions. The abdominopelvic cavity has a superior part—the abdominal cavity—and an inferior part—the pelvic cavity. The organs listed, including the stomach, much of the small and large intestine, liver, gallbladder, spleen, and pancreas, are classic abdominal organs. The kidneys and adrenal glands sit on the posterior abdominal wall within this same region (retroperitoneal), so they belong to the abdominal cavity as well. The pelvic cavity, by contrast, contains pelvic organs like the bladder and reproductive organs and does not include these digestive organs. Therefore, the superior portion that contains all the listed organs is the abdominal cavity.
