Question

part a
if a surgeon makes an incision just inferior to the diaphragm, which body cavity will be opened? (module 1 22c)
pelvic portion of the abdominopelvic cavity
vertebral cavity
pleural portion of the thoracic cavity
peritoneal portion of the abdominopelvic cavity
pericardial portion of the thoracic cavity

Explanation:

The diaphragm separates the thoracic cavity from the abdominopelvic cavity. An incision just inferior to the diaphragm would open the peritoneal portion of the abdominopelvic cavity. The pleural and pericardial portions of the thoracic cavity are above the diaphragm, the vertebral cavity is posterior and not related to this location, and the pelvic portion of the abdominopelvic cavity is more inferior.

Answer:

peritoneal portion of the abdominopelvic cavity
