Milky Alveolar Duct

The milky alveolar duct (ductulus alveolaris lactifer) is a narrow canal that connects the alveoli of the mammary gland with the milk ducts and is one of the main elements of the milk flow system. It consists of many small alveoli that are filled with mammary gland secretions, which are then transferred into the milk ducts.

The alveolar ducts play an important role in the process of milk ejection, as they ensure a constant flow of milk from the alveoli to the milk ducts and back. In addition, they are also involved in regulating the levels of hormones necessary for milk production.

Alveolar milk ducts have a length of 2 to 4 mm and a diameter of about 0.2 mm. They pass through the breast tissue and end in the milk ducts, which connect to the nipples.

One of the functions of the mammary alveolar ducts is to ensure a constant flow of milk from the alveoli of the mammary gland into the milk ducts, which is necessary to maintain the level of hormones in the body and the normal functioning of the mammary gland.

In addition, the milky alveolar ducts play an important role during breastfeeding. During feeding, milk from the milk ducts flows into the baby's mouth, where he can suck it. This allows the mother to provide her baby with the necessary amount of milk, which is an important factor for his growth and development.

Thus, the mammary alveolar ducts are an important element of the milk supply system and play an important role in both milk production and infant feeding.



The milk duct is a small tubular canal that connects the alveolar lobes of the mammary gland to the nipple. This is an important element in the process of milk secretion and maintaining lactation. There are two forms of milk ducts. The apical ducts begin from the alveoli and ascend to the nipple towards the base of the breast. The basal ducts are located from the base of the breast and connect to the apical ducts, which then go to the nipples
