First line of defense
This line of defense is non specific and is meant to stop microbes from entering the body.
Our skin and membranes act as a barrier. From the mucus into our nasal way to the blood clot that is produce when the skin is cut , ours bodies are well protected. But sometimes, the first line of defense is not enough and our body must use its second line of defense.
Second line of defense
This line of defense is activated when microbes manage to get inside the body. A type of white blood cells , called Phagocytes, are released. They will surrender the invaders and ''swallow'' them.
Third line of defense
This line of defense is the immune response. When a microbe invades the body, the immune system makes antibody against it. It is then a battle between the antigen( intruder) against the antibody(immune system).
Once the intruder has been destroyed , the immune response winds down. The body will then produce memory cells which will ''remember'' which antibodies to use to fight the invader. If the person would come into contact to this same disease, the body will make the right antibodies and quickly destroy the pathogen preventing symptoms of the disease reappearing.
