Question

Quizplus · Accepted Answer

Oxytocin is the hormone responsible for the ejection of milk from the alveoli into the ducts during lactation. Prolactin stimulates milk production, but oxytocin is necessary for the actual release of milk from the breast. Estrogen and progesterone play important roles in preparing the breast for lactation during pregnancy, but are not directly involved in the ejection of milk during lactation.
