The Lungs Lie in the ________ Cavity

Question

The lungs lie in the ________ cavity.
A) dorsal
B) mediastinum
C) pleural
D) pericardial

Accepted Answer

The lungs are surrounded by a double-layered serous membrane called the pleura, which lines the thoracic cavity and covers the lungs. Therefore, the lungs lie in the pleural cavity. The dorsal cavity contains the cranial cavity and spinal cavity. The mediastinum houses the heart, great vessels, esophagus, and trachea. The pericardial cavity is a potential space between the parietal and visceral pericardium that surrounds the heart.
