Question

The thoracic cavity contains the
A) coelom.
B) pericardial cavity.
C) pelvic cavity.
D) pleural cavities.
E) pericardial and pleural cavities.

Accepted Answer

The thoracic cavity contains both the pericardial cavity (which surrounds the heart) and the pleural cavities (which contain the lungs). Therefore, the correct choice is E, which includes both the pericardial and pleural cavities. Choices A, C, and B are incorrect because they do not specifically refer to the structures within the thoracic cavity, and choice D is incorrect because it only refers to the pleural cavities and not the pericardial cavity.
