Quizplus · Accepted Answer

The collapse of the left lung indicates that the bullet entered the pleural cavity, which is the space between the lungs and the inner walls of the chest. The mediastinal cavity contains the heart and other organs of the chest, while the pericardial cavity specifically contains the heart. The vertebral cavity contains the spinal cord, and the cranial cavity contains the brain.
