Smallest functioning unit of the breast is called what?

Explanation:
The smallest functioning unit of the breast is the acinus. These tiny secretory clusters are where milk is produced, with secretory cells lining a central lumen. Several acini come together to form a lobule, and lobules drain through ducts that merge into the lactiferous ducts toward the nipple. So, while a lobule is a larger grouping and a duct is the passageway for milk, the actual production happens at the acini, making them the smallest functional unit.
