Breast Structure and Their Fuction

From the post below, you know what the compose of breast right? Ok, I repeat, the breast is complicated with the network of milk producing sacs, passageways for carrying milk, supporting tissue, tiny muscles, lymph nodes, gland and fat. Complicated right? Not only fat ! Breast tissue is a complex network of lobule and mammary duct i a pattern resembling bunches of grapes on their stems.

The lobules are spherical-shaped sacs that produce milk, and the ducts are the canals that carry milk from the lobules to the nipple openings when a woman is breastfeeding. The tiniest ducts attached to lobules join together like the branches of grape stems into increasingly larger ducts. There are between five and ten ductal systems in each breast, each with its own opening at the nipple. Each breast has up to about a million lobules

Muscle tissue in the nipple allows it to become erect in response to sexual stimulation or breastfeeding. There is also muscle tissue around the lobules that helps squeeze milk into the ducts. Glands on the areola, the shaded circle of skin surrounding the nipple, secrete small amounts of fluid to lubricate the nipple when breastfeeding [2,3]. Figure 1.1 shows the different parts of the breast.
