Breasts are modified sudoriferous (sweat) glands which produce milk in women. The breasts of a female  contain the mammary glands, which secrete milk used to feed infants. Each breast has one nipple surrounded by the areola. The areola has several sebaceous glands. In women, the larger mammary glands within the breast produce the milk. These are drained to the nipple by 4 to 18 lactiferous ducts, where each duct has its own opening. The remainder of the breast is composed of connective tissue, adipose tissue (fat), and Cooper's ligaments.
