Lactiferous ducts form a tree branched system connecting the lobules of the mammary gland to the tip of the nipple. They are also referred to as galactophores, galactophorous ducts, mammary ducts, mamillary ducts and milk ducts.

When a woman is not lactating, the lactiferous duct is frequently blocked by a keratin plug.
