The document discusses the anatomy of the trunk, which has 4 main parts: the neck, thorax, abdomen, and pelvis. The trunk contains 3 cavities - the thoracic, abdominal, and pelvic cavities. The thoracic cavity contains the heart, lungs and other organs, while the abdominal cavity houses the digestive organs.
