The ventral body cavity is divided into two major cavities, the superior ________ cavity and the inferior ________ cavity.

Question

Quizplus · Accepted Answer

The ventral body cavity is divided into two major cavities, the superior thoracic cavity (which contains the heart, lungs, and other structures) and the inferior abdominopelvic cavity (which is further divided into the abdominal cavity and the pelvic cavity). Therefore, option B is the correct answer. Option A is incorrect because the mediastinum is a region within the thoracic cavity, not a separate cavity. Option C is incorrect because it separates the abdominal and pelvic cavities, which are both within the abdominopelvic cavity. Option D is incorrect because the pericardial cavity is a small, fluid-filled space within the thoracic cavity that surrounds the heart, but it is not a major cavity.
