The biological function of the breast is to produce milk in order to nourish an infant.

Structure of the breast

The breast has a complex structure. Each breast (also called a mammary gland) is composed of fifteen to twenty compartments separated by fatty tissue which gives the breast the shape we recognise. Each of these compartments is made up of lobules and ducts. The role of the lobules is to produce milk during lactation, and the ducts then transfer the milk to the nipple.
