Melkekanaler

Melkekanaler, also known as milk ducts, are a vital part of the mammalian mammary gland. These are essentially a network of tubes that transport milk from the lobules, where it is produced, to the nipple, where it can be expelled. In humans, these ducts are lined with epithelial cells and are surrounded by smooth muscle, which can contract to help with milk ejection during breastfeeding. The number and branching pattern of these ducts can vary between individuals and species. During pregnancy, the ductal system undergoes significant development and proliferation, preparing for lactation. After childbirth, hormonal signals stimulate the production and release of milk into these channels. The process of milk letdown, or ejection, is a complex physiological reflex triggered by the baby's suckling or the sight and sound of a baby, leading to the release of oxytocin. This hormone causes the muscles around the ducts to contract, pushing milk towards the nipple. Issues with milk ducts can lead to various conditions, including blockages, infections like mastitis, or inflammation. Understanding the anatomy and function of melkekanaler is fundamental to understanding lactation and breastfeeding.
