MICROANATOMY

Detailed explanation-1: -Prolactin. Prolactin is necessary for the secretion of milk by the cells of the alveoli. The level of prolactin in the blood increases markedly during pregnancy, and stimulates the growth and development of the mammary tissue, in preparation for the production of milk (19).

Detailed explanation-2: -Prolactin contributes to hundreds of physiologic functions, but the two primary responsibilities are milk production and the development of mammary glands within breast tissues. Prolactin promotes the growth of mammary alveoli, which are the components of the mammary gland, where the actual production of milk occurs.

Detailed explanation-3: -The prolactin tells the milk glands in your breasts to make more breast milk, and the oxytocin is responsible for getting the breast milk from your breasts to your baby. 2 As long as you continue to breastfeed (or pump) very often, your body will continue to release prolactin, and you will continue to make milk.
