brain - Vertebral cavity runs within the vertebral
column encases the spinal cord

- Mediastinum contains the pericardial cavity
surrounds the remaining thoracic organs - Pericardial cavity encloses the heart

Body CavitiesAbdominopelvic
- The abdominopelvic cavity is separated from the
superior thoracic cavity by the dome-shaped
diaphragm - It is composed of two subdivisions
- Abdominal cavity contains the stomach,
intestines, spleen, liver, and other organs - Pelvic cavity lies within the pelvis and
contains the bladder, reproductive organs, and
