How do white blood cells protect the body from bacteria?

Answer 1

If an infection occurs and bacteria enters your body the white blood cells will produce antibodies to cover them and clump them together, then more white blood cells will engulf them and digest them. A lot of the white blood cells will then die but a few will stay alive as memory cells and if that bacteria enters again they will multiply and fight it before any harm is done. Platelets in the blood will also seal the wound that has been made to prevent any further dirt and bacteria from entering the body. Once you have had a disease the antibodies are produced much quicker the next time you catch the same infection and your body also has some immunity to it.

Answer 2

White blood cells, more specifically neutrophils, protect the body from bacteria by engulfing it in a process called phagocytosis.

1. The neutrophil detects certain chemicals on the surface membrane of the bacterium to determine whether it is harmful.
2. Once identified as harmful it is engulfed.
3. The bacterial cells is digested.
4. The products from this cell are then absorbed by the neutrophil.

Answer 3

the white blood cells "eat" the viruses or germs and destroy it inside its body
