Quizplus · Accepted Answer

The diaphragm separates the thoracic cavity, which includes the heart, lungs, and other organs of the chest, from the abdominopelvic cavity, which includes organs of the digestive system, reproductive system, and urinary system, as well as the pelvic bones and muscles. Choice A (pleural and mediastinum) and Choice C (pericardial and pleural) both refer to cavities within the thoracic cavity, but not the entire thoracic cavity itself. Choice D (abdominal and pelvic) refers only to the lower half of the body and does not include the thoracic cavity. Choice E (pericardial sac and pericardial) refers only to the sac surrounding the heart, not the entire thoracic cavity.
