The ability of the body to resist foreign microorganisms, such as bacteria, parasites, and viruses, is known as Immunity.
What is Immunity?
The body's defense against infection is provided by the immune system, a complex network of organs, cells, and proteins that also safeguards the body's own cells. Every germ (microbe) that the immune system has ever eliminated is recorded, allowing it to promptly identify and eliminate the microbe if it re-enters the body.
The immune system works to identify and eliminate foreign substances (known as antigens) that the body detects. Antibody production is induced in B lymphocytes (also called immunoglobulins). Specific antigens are locked onto by these proteins.
