Milk flows from many lobes through lactiferous ducts that converge toward the nipple, where multiple tiny openings allow milk to reach the surface. The nipple commonly has a dozen or so openings, with counts typically described as a range around five to fifteen. This reflects natural variation between individuals while illustrating that there isn’t just a single duct opening. Recognizing there are multiple openings explains why nipple anatomy presents as several small openings rather than a single pore, and it helps in understanding patterns of breastfeeding, ductal drainage, and potential sources of nipple discharge.
