what are the two main cavities in the human body?
- the dorsal cavity
- the ventral cavity
the dorsal cavity is divided into…
- the cranial cavity (formed by the skull, which contains the brain)
- the spinal cavity (formed by the spine, which contains the spinal cord)
the ventral cavity is divided into…
- the thoracic cavity (which contains the heart and lungs)
- the abdominopelvic cavity (which is further divided into the abdominal cavity and the pelvic cavity)
what does the abdominal cavity contain?
it contains the liver, stomach, intestines, and kidneys
what does the pelvic cavity contain?
it contains the urinary bladder and reproductive organs
