Galactophore, also known as lactiferous duct, refers to the milk-carrying duct or tube that transports breast milk from the milk-producing mammary glands to the nipple. It plays a crucial role in the process of breastfeeding in mammals, including humans.
In female mammals, including humans, the galactophores are an essential component of the mammary gland system. These ducts branch out from each mammary gland, which are composed of secretory cells that produce and store milk. The galactophores collect and carry the milk from these glands, directing it towards the nipple. They form an intricate network within the breasts, allowing milk flow and transport, enabling the lactating female mammal to feed their offspring.
Galactophores are lined with specialized secretory cells that produce the components of breast milk, including proteins, carbohydrates, fats, vitamins, minerals, and immune factors. These nutrients are synthesized and released into the ducts, creating a nutrient-rich mixture that nurtures the newborn offspring.
During breastfeeding, the act of suckling stimulates nerve endings in the nipple, triggering the contraction of muscles surrounding the galactophores. This contraction helps propel the milk through the ducts towards the nipple so that it can be readily accessed by the nursing infant.
Understanding the structure and function of galactophores is crucial for lactation consultants, healthcare professionals, and individuals experiencing difficulties with breastfeeding.
