Different components make up the breasts, and all these components work together to achieve a common goal.

The parts of the breast are:

3. Chest wall

This particular part of the breast provides support for breathing and movement of the upper arms and shoulders.

The chest bone consists of the ribs, breastbone (this can be felt between the breasts), and the spine. 

The chest wall comprises the following functional parts:

  • Skin
  • Fat
  • Muscles
  • Bones and other tissues

These functional parts help to protect the organs between the neck and abdomen. 

4. Lobules

The lobules are essential glands that act as the engines for the production of milk. They are a collection of lobes, and a woman’s breast consists of about 15 to 20 of them.

One important thing to note is that the lobules are the starting point of some breast cancers. Lobules are generally not present in the male breasts as they lack the milk-producing ability. 

5. Areola

This essential part is the darker pigmented, round area that surrounds the nipple. It possesses tiny bulges on its surface called the sebaceous glands. These glands bear oily discharge that prevents the areola and nipples from breaking. 

6. Nipple

The nipple is the lifted protrude part at the center of the areola. Attached to the nipple are about 15 to 20 ducts. The nipple permits an opening for the flow of milk during breastfeeding. It also comprises regular muscles that are responsible for the firmness of the nipples.

7. Ducts

These are the channels through which milk flows from the lobules to the nipple.

8. Fatty tissue

The fatty tissue is responsible for the size of the breast. When it combines with fibrous tissues, they make up the connective tissues containing the breast’s systems.

When the estrogen level rises at maturity, it triggers the accumulation of fatty tissues and gland tissues, thereby increasing the female breasts’ size. 

9. Lymph nodes

These are tiny special organs that are found all around the body. They produce watery substances called lymph that accommodate the lymphocytes.

Lymphocytes are immune cells that help combat diseases and infections. The lymph vessel moves purified lymph fluid from the breast to the lymph nodes.
