Question

Quizplus · Accepted Answer

The sperm will enter the pelvic cavity after passing through the vagina. The thoracic cavity contains the chest organs, the pericardial cavity contains the heart, the dorsal cavity contains the spinal cord, and the pleural cavity contains the lungs. None of these cavities provide a direct route for sperm to reach the egg.
