Cat Scratch Disease Anatomy

To better understand cat scratch disease, it helps to understand the anatomy of the lymphatic system.

The lymphatic system is a complex arrangement of vessels responsible for transporting cells known as lymphocytes that fight infection. There are two main types of lymphocytes: B-cells and T-cells.

The lymph vessels are interrupted in some areas by swellings known as lymph nodes. The nodes act as filters to fight infection in the body. The lymph nodes can enlarge in response to inflammation. This may be secondary to cancer or an infection (viral or bacterial) in the body.
