what is Immunity what it means
Immunity comes in two flavors: active and passive.
Activated Defense
– When the immune system produces antibodies against a diseased organism after being exposed to it, the condition is known as active immunity.
Passive Immunity
– When a person receives antibodies to a disease instead of making them on their own through the immune system, this is known as passive immunity.
How is the immune system functioning?
When the immune system functions as it should, it:
– distinguishes between cells that belong in your body and those that don’t.
– mobilizes and activates to destroy potentially harmful bacteria.
– terminates an attack after the danger has passed.
– produces antibodies against pathogens and learns about them after coming into contact with them.
