There are three main body cavities:
- Thoracic cavity: Formed by the rib cage, sternum, thoracic vertebrae, and the diaphragm. Contains the heart, lungs, trachea and oesophagus.
- Abdominal cavity: Extending from the diaphragm to the pelvis, formed by the lumber vertebrae and abdominal muscles. Contains the stomach, liver, gallbladder, pancreas, spleen, kidneys, most of the small and large intestines and the lower part of the oesophagus.
- Pelvic cavity: Formed by the sacrum, coccyx, ilium and iscium. Contains the lower parts of the small and large intestine, the bladder, and the female reproductive organs.
