Your body’s cavities are basically the “holes” that would be left (besides bones and tissues forming the space) if you removed your internal organs. Your body has two main cavities; the dorsal and ventral.

  • Ventral cavity: Extends from just under the chin to the pelvic area, encompassing the thoracic cavity, diaphragm, and abdomino-pelvic cavity

    • Thoracic cavity: Contains the heart and lungs

    • Abdomino-pelvic cavity: Contains the organs of the abdomen and pelvis

  • Dorsal cavity: Contains posterior body organs extending from the cranial cavity into the vertebral canal housing the spinal cord

    • Spinal cavity: Enfolds and protects the spinal cord

    • Cranial cavity: Inside the skull and enclosing the human brain
