Breast Milk

Mother with Visible Cardiovascular System

When a mother's digestive system breaks down food nutrients are absorbed into her bloodstream. The nutrients travel to capillaries in the breast tissue where they are taken up by lactocytes (milk-producing cells) and repackaged into breast milk.

Breast milk is the milk produced by the breasts (or mammary glands) of a human female for her infant offspring. Milk is the primary source of nutrition for newborns before they are able to eat and digest other foods; older infants and toddlers may continue to be breastfed, either exclusively or in combination with other foods.
