Tejcsatornák

Tejcsatornák, also known as lactiferous ducts, are a crucial part of the mammary gland responsible for transporting milk from the alveoli to the nipple. These small, tube-like structures begin as a network of fine tubules within the glandular tissue and gradually merge to form larger ducts. Typically, there are several main lactiferous ducts, each leading to a separate opening on the surface of the areola, surrounding the nipple.

The lining of these ducts is composed of epithelial cells that play a role in milk flow and protection. During lactation, the muscle fibers surrounding the alveoli and ducts contract, aiding in the ejection of milk. The size and diameter of the lactiferous ducts can vary among individuals and may change during different stages of a woman's reproductive life. They are essential for breastfeeding, enabling the transfer of milk to an infant. Any blockages or inflammation within these ducts can lead to conditions such as mastitis or milk blisters, impacting milk production and causing discomfort. Understanding the structure and function of tejcsatornák is fundamental to comprehending the physiology of lactation.
