What is the channel that carries milk from the lobes of the breast to the nipple called?

• A. Lactiferous ducts
• B. Ducts of Santorini
• C. Alveolar ducts
• D. Mammary ducts

Answer: (A)

Milk produced in the breast comes from the lobes’ alveoli and is collected by a network of ducts. The main channel that carries milk from these lobes toward the nipple is the lactiferous ducts. They unite the milk from multiple lobes, extend toward the nipple, and often form small lactiferous sinuses beneath the areola before it exits at the nipple openings. Ducts of Santorini are accessory ducts and may drain portions of the breast, but they are not the primary path from the lobes to the nipple. Alveolar ducts are the smaller ducts inside the lobules that feed into the main lactiferous ducts rather than serving as the main conduit to the nipple.
