Explanation:
Pregnancy hormones cause the milk ducts to grow in number and size. ... Prompted by the hormone prolactin, the alveoli take proteins, sugars, and fat from your blood supply and make breast milk. A network of cells surrounding the alveoli squeeze the glands and push the milk out into the ductules, which lead to the ducts.
