A lymph node is an oval-shaped organ of the lymphatic system, distributed widely throughout the body including the armpit and stomach and linked by lymphatic vessels. Lymph nodes are major sites of B, T, and other immune cells.ymph nodes are bean or oval shaped and range in size from a few millimeters to about 1â2 cm long. Each lymph node is surrounded by a fibrous capsule, and inside the lymph node the fibrous capsule extends to form trabeculae. The substance of the lymph node is divided into the outer cortex and the inner medulla.
Lymph nodes are small clumps of immune cells that act as filters for the lymphatic system. The lymphatic system runs throughout the body (like the circulatory (blood) system) and carries fluid and cells. The lymph nodes in the underarm (the axillary lymph nodes) are the first place breast cancer is likely to spread.Figure 4.4 shows the location of the axillary lymph nodes.he lymphatic system runs throughout the body (like the circulatory (blood) system) and carries fluid and cells.
