Extra info for Thymus
A
T lymphocytes (T cells): T cells control your body’s immune system response and directly attack and kill infected cells and tumor cells.
Throughout your childhood years, white blood cells called lymphocytes pass through the thymus, where they are transformed into T cells.
After the T-cells have matured, they enter your bloodstream. They travel to your lymph nodes (groups of cells) and other organs in your lymphatic system, where they help your immune system fight disease and infection.
