ANATOMY
A
breast's shape is essentially determined by the amount of
Fatty Tissue it contains. Under the skin, a
breast is made up of Fatty Tissue, Milk Glands
(where milk is made by specialized cells), and Milk Ducts
(lactiferous ducts) that carry the milk from the gland to
the Nipple.
Milk
glands do not usually make milk unless they are triggered
by the hormones of pregnancy. Once triggered, the
glands produce as much milk as is needed by the baby (often
more than a quart a day)! Therefore, during pregnancy
and nursing, a woman's breast become much larger than when
not pregnant because it is literally full of milk and bigger
glandular tissue.
