Also know as White Blood Cells.
These Cells help protect the body from becoming infected by Viruses and Bacteria. They help your body fight Antigens [Foreign threats in your body]. They are an important part of your immune system.
There are three types of LYMPHOCYTES: B Cells, T Cells, and NK Cells (Natural Killer Cells).
LYMPHOCYTES are produced in your Bone Marrow. Some enter your blood stream. Others enter your Lymphatic System.
About 25% of new LYMPHOCYTES remain in your Bone Marrow and become B Cells. The other 75% travel to your Thymus [Lymphoid Gland] and become T Cells.
