White Blood Cells
In the event that microbes enter the body, they need to be neutralised or killed. This is done by white blood cells. These cells:
- engulf and digest microbes
- produce antibodies to neutralise microbes
- produce antitoxins to neutralise the toxins produced by microbes
Antibodies
Antibodies are produced in the following manner:
1. White blood cell "sees" antigen (microbe)
2. Cell produces antibodies to "fit" antigen
3. Antibodies fit onto antigens and cause them to "clump"
4. Antigens are "eaten" (broker down) by white blood cells
