List the body cavities
Cranial Cavity Vertebral Cavity Thoracic Cavity Abdominopelvic Cavity - Abdominal Cavity - Pelvic Cavity
Cranial Cavity
Contains the brain
Vertebral Cavity
Anterior surface of torso; divided by diaphragm muscle into upper thoracic cavity and abdominopelvic cavity
Thoracic Cavity
The chest; contains trachea, bronchi, lungs, esophagus, heart and great blood vessels, thymus gland, lymph nodes, and nerves. Contains smaller cavities, too (Pleural and Pericardial)
Abdominopelvic Cavity
Imaginary line that runs across hipbones divides the body into the abdominal and pelvic cavities.
Abdominal Cavity
Contains stomach, liver, gallbladder, pancreas, spleen, kidneys, and intestines (small and large), ovaries (in female); the peritoneal cavity (peritoneum) surrounds the abdominal organs
Pelvic Cavity
contains colon, rectum, urinary bladder, uterus (in females)
