Milk secreting organs on the front of the chest of women are called breasts. These are human mammary glands composed mainly of fat cells. Word mammary came from Latin word “mamma”, which is derived from the cry “mama” voiced by infants. Mammary glands consist of a complex network of branching tubes. These tubes are known as ducts. These ducks exit from lobules. Lobules are the glands which produce milk in females. Ducks transport milk from the lobules out to the nipple. The breasts grow further and the amount of milk producing tissues increases during the pregnancy. Breast is actually an important part of the body structure of all the living beings especially in the mammals. Breast contains milk producing glands which secrets through the nipples for the feeding of kids. The specific shape of the breast is due to the tissues present under the skin. In human beings, breasts are also considered as the symbol of beauty and attractions as well. There is no standard size of breasts. It varies according to individual and age factor. At the time of the pregnancy, breasts size grows due to the increasing amount of milk produce tissues.

The word breast also turn to the upper ventral section of an animal’s chest, chiefly that of mammals, including human beings. The breasts of a female mammal’s body have the mammary glands, which exude milk used to feed newborn babies. In this article, we deal with the human breast; for other animals, see udder and mammary gland. Breasts are more able to be seen on adult women, but male humans also have breasts, which generally are less important. The breasts are customized soporiferous (sweat) glands, making milk in females. Each breast contains one nipple bordered by the areola. The areola is highlighted from pink to dark brown and has more than a few sebaceous glands.

In females, the superior mammary glands within the breast make the milk. They are circulated all through the breast, with two-thirds of the tissue initiate within 30 mm of the base of the nipple. These are exhausted to the nipple by connecting 4 and 18 lactiferous tubes where each tube has its own opening. The network produced by these tubes is difficult, like the scrambled roots of a tree. It is not always approved completely, and branches getting ready to the nipple. The tubes near the nipple do not proceed as milk tanks. The remnants of the breast are self-possessed by connective tissue. The percentage of glands to adipose tissues goes up from 1:1 in no lactating women to 2:1 in lactating women. The breasts meet over the pectoralis main muscle and generally enlarge from the level of the 2nd beam to the level of the 6th beam interiorly.
