The tunica vaginalis is a serous membrane associated with which organ?

Explanation:
The tunica vaginalis is a serous membrane that surrounds the testes in the scrotum. It develops from the peritoneum as the testis descends, forming a two-layer sac (visceral covering the testis and parietal lining the cavity) with a small potential space between them that contains serous fluid to lessen friction during movement. Other options tie to different serous membranes: the heart is lined by the pericardium, the lungs by the pleura, and the liver by peritoneum.
