Detailed explanation-1: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.
Detailed explanation-2: -The immune system recognizes invaders by their antigens, which are proteins on the surface of the invading cells (see Figure 1). Every cell or substance has its own specific antigens, and a person’s cells carry “self-antigens” that are unique to that individual.
Detailed explanation-3: -The body’s immune system helps prevent or limit infection. One way the body fights foreign invaders, like bacteria and viruses, is by making antibodies against them. An antibody is a Y-shaped protein that’s produced by white blood cells.
