Breast Structure with Lymph Nodes

Image Description:

Breast tissue extends from the collarbone to the lower ribs, sternum (breastbone), and armpit. Each breast contains 15-20 sections called lobes and each lobe has many smaller sacs, or lobules (glands). It is these lobules that produce milk in breastfeeding women. The lobes and lobules are connected to the nipple by tubes called ducts, which carry milk to the nipple. The nipple is located at the centre of the areola, the dark area of skin surrounding the nipple.

The breast and armpit contain lymph nodes that belong to the lymphatic system- a network of nodes and tubes that drain fluid (lymph) and transport white blood cells (immune cells involved in fighting against infections). The remainder of the breast consists of fatty and connective (or fibrous) tissue.
