The secretion of milk from the mammary glands is known as [[Lactation - Overview of Lactation - Anatomy & Physiology|lactation]] - the milk provides nourishment for the neonate in addition to immunoprotection in the form of anitibodies which are contained in the initial mammary secretions, or colostrum. Lactation continues until the neonate is weaned; after weaning the mammary glands undergo involution and return to a non-secretory state.
