What is the primary function of the ducts within the breast?

The primary function of the ducts within the breast is to transport milk to the nipple. These ducts play a crucial role in the breastfeeding process, as they act as pathways for milk produced in the lobules of the breast to flow down and be delivered to the nipple, where it can then be accessed by the nursing infant. This transport mechanism is essential for successful breastfeeding, ensuring that the baby receives the necessary nourishment.

While other structures within the breast have important roles—such as the supporting tissues providing structure, or other glands potentially involved in hormone production—the specific anatomical function of the ducts is centered around the delivery of milk during lactation, making them vital for the breastfeeding relationship. The lubrication of the nipple is typically managed by other mechanisms and does not pertain to the primary function of the ducts.
