Answer:
memory cells
Explanation:
Your body recognizes the bacteria as an invader because of the proteins shape on the surface of it. The shapes are different than those of the ones in the human body.
- White blood cells work together to fight the invaders. One type of the white blood cells make antibodies to fight the invaders. They stick to the bacteria's surface which kills the bacteria or disables them.
-Eventually your body will get rid of all the bacteria and you'll recover. Some white blood cells then become memory cells.
------Memory cells will help you fight off the bacteria if they invade the body again. The immune system will respond so quickly that you won't get sick.
