Answer 1

Once the invading microbes have been destroyed the immune response winds down. Once a person has had a disease they don't normally catch it again because the body produces memory cells that are specific to that antigen.

Answer 2

Answer:

Concept:

   The body uses antibodies to fight off microorganisms and the toxins (poisons) they release. They accomplish this by identifying molecules known as antigens that indicate the microbe or toxin as being foreign on its surface or in the chemicals it produces. These antigens are then designated for eradication by the antibodies.

Explanation:

• When an antigen enters the body and B-cells are able to recognise it, they will produce antibodies (either by prior exposure to the disease or through vaccination against it). Think of a lock and key system. The immune system is activated to attack and get rid of invaders when antibodies connect to an antigen.
• When an antibody is bound to a particular antigen, immune cells can more quickly eliminate it. T cells actively combat antigens to help control the immune response. Additionally, they release cytokines, which control the entire immune response.
• As a result, the body remembers the bacteria and produces antibodies against them right away when they attack again.
