Skin

"The skin is the largest organ of the body, with a total area of about 20 square feet. The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold.
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The skin’s color is created by special cells called melanocytes, which produce the pigment melanin. Melanocytes are located in the epidermis."

Pelvic disease

Pelvic inflammatory disease (PID) is an infection that passes from the vagina through neck of the womb (cervix), the womb (uterus) and up to the Fallopian tubes. The ovaries are sometimes also involved. Bacteria and other micro-organisms can find their way through the vagina and the cervix to the internal reproductive organs. A bacterial infection can cause inflammation in these organs and their surroundings. This most commonly occurs in the Fallopian tubes.
