Answer to Question 1

ANS: D
Hormones play important roles in initiating milk production, but once lactation is established, infant suckling becomes the primary stimulus.

Answer to Question 2

ANS: B
Infant suckling causes the posterior pituitary gland to secrete oxytocin, producing the let-down, or milk ejection, reflex, causing the milk to be delivered from the alveoli (milk-producing sacs) to the nipple.
