Lymphocyte cells produce antibodies that destroy bacterial antigens. It is the best, active, powerful and permanent defense system. This defense system is:
- Detects and targets foreign microbes. Separates healthy cells from diseased and dead cells.
- Kills specific germs and keeps them in memory and prevents attacks from those germs for years.
- The immune system can be effective in any part of the body and protects the whole body.
