Lactiferous duct - Wikipedia
Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland. When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.

2023年12月10日 · One lactiferous duct drains 15 to 20 lobes. These ducts enlarge to form the lactiferous sinus before they open separately into the nipple. Milk collects in the lactiferous sinuses and is released in response to the baby's suckling. The lactiferous ducts are arranged radially in the nipple.
