Explain the process of lactation.

(N/A) The mammary glands of the female undergo differentiation during pregnancy and start producing milk towards the end of pregnancy by the process called lactation.
The milk produced during the initial few days of lactation is called colostrum,which contains several antibodies,primarily $IgA$.
Breast-feeding during the initial period of infant growth is recommended by doctors for bringing up a healthy baby.
The synthesis of milk in the mammary glands is stimulated by the hormone prolactin,which is secreted by the anterior pituitary gland.
