The abdominal cavity contains organs such as the stomach, liver, gallbladder, pancreas, and spleen.

• A. Stomach, Liver, Gallbladder, Pancreas, And Spleen
• B. Heart, Lungs, Trachea
• C. Kidneys, Bladder
• D. Brain, Spinal Cord

Answer: (A)

This question tests which organs belong to the abdominal cavity. The stomach, liver, gallbladder, pancreas, and spleen are classic organs housed in the abdominal cavity, all associated with digestion and related functions. In contrast, the heart, lungs, and trachea are in the thoracic cavity; the brain and spinal cord are in the cranial and vertebral spaces; and while kidneys sit in the abdomen as retroperitoneal structures and the bladder is in the pelvic cavity, they are not all strictly within the abdominal cavity. So, the group listing the stomach, liver, gallbladder, pancreas, and spleen is the correct one.
