Breast Anatomy and Milk Flow Explained | How Milk Travels Through the Mammary Glands

During pregnancy and breastfeeding, the mammary glands undergo major changes to support milk production. Milk ducts expand and branch under the influence of hormones such as estrogen, progesterone, cortisol, and prolactin. Small sac-like structures called alveoli develop and are lined with milk-secreting cells known as lactocytes. These are surrounded by contractile epithelial cells that help push milk forward. Milk is produced by lactocytes, fills the alveoli, and is pushed into the milk ducts. Groups of alveoli form lobules, and breastfeeding mothers typically have 12–20 lobules arranged around the nipple. Milk then flows through the ducts into small reservoirs and exits through tiny openings in the nipple. The dark area around the nipple, called the areola, contains Montgomery glands, which release natural oils to clean and protect the nipple, helping prevent cracking during breastfeeding. This video explains the detailed anatomy of the breast and how milk flows naturally from the glands to the baby. #breastanatomy #milkducts #lactationprocess #breastfeedingeducation #mammaryglands #howbreastmilkworks #newmomtips #postpartumcare #breastfeedingbasics
