On the walls of the lactocytes (milk - producing cells of the alveoli) are prolactin receptor sites that allow the prolactin in the blood stream to move into the lactocytes and stimulate the synthesis of breastmilk components.

As milk empties from the alveolus, increasing numbers of prolactin receptors return to their normal shape and allow prolactin to pass through — thus rate of milk synthesis increases.

When the alveolus is full of milk, the walls expand / stretch and alter the shape of prolactin receptors so that prolactin can not enter via those receptor sites — thus rate of milk synthesis decreases.

When your baby stimulates your breast by suckling (or even when you think of your baby, hear your baby's cry, smell your baby's scent or look at a picture of your baby), your body releases oxytocin and prolactin that triggers a «let down» so milk flows from the alveoli to the milk ducts.
