Which cavity contains the stomach, liver, and spleen, along with other digestive and accessory organs?

• A. Pleural cavity
• B. Abdominal cavity
• C. Pericardial cavity
• D. Mediastinum cavity

Answer: (B)

The main idea here is recognizing where the stomach, liver, and spleen are located. These organs reside in the abdominal cavity, which sits below the diaphragm and contains most digestive and accessory organs like the stomach, liver, spleen, as well as parts of the intestines and related structures. The abdominal cavity is part of the larger abdominopelvic region, separated from the thoracic area by the diaphragm.

In contrast, the pleural cavity is the space for the lungs, the pericardial cavity surrounds the heart, and the mediastinum is a central compartment within the thoracic cavity that houses the heart, great vessels, trachea, and other structures. None of these contain the stomach, liver, or spleen.
