LACTIFEROUS TUBULES

The lactiferous tubules are the small ducts through which the milk flows to the openings of the nipple in the mammary glands. The lactiferous ducts are composed of areolar tissue and elastic fibres. The number of ducts in each mammary gland varies from fifteen to twenty. These ducts increase in capacity during pregnancy and in breast-feeding the pressure of the baby's gums on the areola stimulates the milk flow.
