During development, the testicles descend through the body cavity into the scrotal sacs. They carry with them connections to the circulatory system and a covering derived from the parietal peritoneum. In the image on the left the testicles have been removed from the scrotal sac and the tunic vaginalis covering them has been partially removed. When enclosed in the tunic vaginalis, the space surrounding the testicles is directly connected to the lower abdominal cavity.

share some of the same pathways. Waste material is transported by the circulatory system to the kidneys. Here it
is removed from the blood and transported from the body.
