The internal male reproductive organs reside in which body cavity?

• A. Abdominal
• B. Thoracic
• C. Pelvic
• D. Spinal

Answer: (C)

The main idea is where the internal components of the male reproductive system are located. In males, the internal reproductive organs—such as the vas deferens, seminal vesicles, and prostate—are housed within the pelvic cavity. The testes, while part of the reproductive system, sit outside the body in the scrotum, so they are not inside a body cavity. The abdominal cavity mainly contains digestive and some other organs, the thoracic cavity contains the heart and lungs, and the spinal canal is a protective space within the vertebral column. So, the pelvic cavity is the correct location for the internal male reproductive organs.
