The breast contains a prominent part called the nipple. The nipples are present in males and females, and they are a group of fatty tissues based on the wall and muscles of the chest.

The nipple takes this inverted shape from birth, and it results from the shortness of the milk ducts that pull the nipple tissues inward, making it difficult for the breastfeeding process.
