A lymph node is an organ made up of many types of cells. The lymph node is also part of the lymphatic system and are found throughout the body acting as filters to keep things that do not belong in the body out. The lymph nodes are centralized in the cervical, axillary, and inguinal. They are located close to the portages of entries. All the lymph nodes are routed through the right lymphatic duct or on the left side which is the left thoracic duct.
They are an important part of the immune system because the lymph nodes contain white body cells. When the lymph nodes become enlarged or inflamed, the conditions that this can cause can be anything from a throat infection to cancer. The lymph node is surrounded by a fibrous capsule and is divided into the outer cortex and inner medulla. Inside the lymph node, a mesh like work called RN (Reticular Network) supports the node. Not only does this mesh work support but it also provides adhesion to the cells inside.The lymph nodes allow the exchange of material with the blood.

I really like how you went in depth about the structure of the Lymph nodes. I didn't put anything like that in mine. I mainly focused on the function and cells involved with it and yours is a very nice change of pace. I also like how you added in the part about throat cancer because that very much hits home for me and it's nice to see that we can now have a better understanding of it.
