The body contains two main cavities, dorsal and ventral, that house and protect the internal organs. These cavities are subdivided to further distinguish location. The dorsal cavity is the space within the skull and the spinal canal.The spinal canal is surrounded by the vertebrae.he pelvic cavity contains the urinary bladder, certain reproductive organs, parts of the large intestine, and the rectum. We call the pelvic and abdominal cavities together the abdominopelvic cavity. (Brooks, 2009) There are two simple ways to divide the abdomen: four quadrants and nine regions.
