The integumentary system of the lower abdomen and pelvis includes the skin and hair of this region. The skin of this system protects against damage to the organs contained within the abdomen. Additionally, the skin over the genitals is the first line of defense against sexually transmitted diseases and other diseases that affect these reproductive organs. Both men and women have hair on the lower abdomen that extends from the lower edge of the chest to the pubis. Hair in the genital region is known as pubic hair.
The integumentary system is made up of the skin and its appendages (such as the nails and the hair). Its primary function is to protect the body from damage. It is also involved in temperature regulation and in the sense of touch. Upon exposure to sunlight, the integumentary system is also the primary vehicle for synthesis of vitamin D.
