Milk-secreting glands of the female breast.
A compound alveolar gland that secretes milk. In women, these glands are made up of lobes and lobules bound together by areolar tissue. Each of the 15 to 20 main ducts, known as lactiferous ducts, discharges through a separate orifice on the surface of the nipple. The dilatations of the ducts form reservoirs for the milk during lactation.
Compound glands of the female breast that can secrete milk. They are made up of lobes and lobules bound together by areolar tissue. The main ducts number 15 to 20 and are known as lactiferous ducts, each one discharging through a separate orifice upon the surface of the nipple. The dilatations of the ducts form reservoirs for the milk during lactation. The pink, or dark-colored, skin around the nipple is called the areola.
