What cavity contains the stomach, intestines, spleen, and liver?

The abdominal cavity is the correct answer because it is specifically designed to house and protect several vital organs, including the stomach, intestines, spleen, and liver. This cavity is positioned between the diaphragm and the pelvis and is an integral part of the human body’s overall anatomy.

Understanding the different cavities can help clarify their functions. The cranial cavity, for instance, contains the brain and is located at the top of the body within the skull. The pelvic cavity, on the other hand, is situated below the abdominal cavity and is primarily associated with reproductive organs and the lower part of the digestive system. The chest cavity, also known as the thoracic cavity, encloses the heart and lungs but does not include the gastrointestinal organs mentioned. Hence, it's clear that the abdominal cavity is the appropriate answer, as it is specifically designated for digestive and some lymphatic organs.
