Alveoli of Mammary Gland
Visualization of the alveoli of the mammary glands. After reproduction has occurred, the essential role of the mammary glands is to provide nourishing milk to a newborn. Internally, the mammary gland consists of up to 25 lobes which radiate around and open to the nipple. The lobes are separated from each other by fat and connective tissue. Within the lobes are smaller lobules which are made up of alveoli that produce milk during lactation. The alveolar glands pass the milk through lactiferous ducts which open to the nipple.
