How do white blood cells fight infection?

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 multipy and fight it before any harm id 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.hello people of earth

Answer 2

Some white blood cells act as scavengers and engulf foreign particles (such as bacteria which can cause infections ) and destroy them. Other white blood cells produce antibodies or destroy dead cells.
