Lymphoma Non-Hodgkin Anatomy
To better understand non-Hodgkin lymphoma, it helps to understand the anatomy of the lymphatic system.
The lymphatic system consists of a network of lymph vessels and lymph nodes throughout the body. The system transports a type of white blood cell, called lymphocytes. These cells play a role in fighting infection.
There are two main types of lymphocytes:
- B lymphocytes
- T lymphocytes
The lymphatic system performs two major functions:
- Stores and transports cells that fight infection
- Removes excess fluid from body tissues
The lymphatic system consists of:
- Lymph vessels:
- A network of vessels throughout the body that transport white blood cells called lymphocytes.
- There are two main types of lymphocytes: B-cells and T-cells.
- Lymph glands:
- The lymph vessels connect in many areas known as lymph nodes.
- The nodes act as filters to fight infection in the body.
- Lymph nodes can enlarge in response to inflammation.
- This can occur due to cancer or an infection nearby the lymph vessels.
- Areas of lymph nodes in the body
- Areas in the body where lymph nodes can be felt
- Abnormal lymph node cells due to Hodgkin's disease
- Lymphatic system around the armpit and breast
- Lymphatic system in the abdomen
