THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The function of the scrotum is to protect the testes and to keep them at a temperature several degrees below the normal body temperature. The scrotum thus protrudes from the body wall: moreover, it contracts from cold, exercise, or sexual stimulation and expands and relaxes when warm.

Detailed explanation-2: -Scrotum-this is a loose bag of skin that hangs outside the body, behind the penis. It holds the testes in place. Testes (or testicles)-these are a pair of egg-shaped glands that sit in the scrotum, on the outside of the body. They produce sperm and testosterone, which is the male sex hormone.
