Detailed explanation-1: -B cells and antibodies together provide one of the most important functions of immunity, which is to recognize an invading antigen and to produce a tremendous number of protective proteins that scour the body to remove all traces of that antigen.
Detailed explanation-2: -They do this by recognising substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign. The antibodies then mark these antigens for destruction. There are many cells, proteins and chemicals involved in this attack.
Detailed explanation-3: -Antibodies are proteins made by the body’s natural defence system (immune system) to fight foreign substances, such as bacteria. Antibodies attach themselves to the foreign substance, allowing other immune system cells to attack and destroy the substance.
Detailed explanation-4: -An antibody, also known as an immunoglobulin, is a large Y-shaped protein produced by B-cells and used by the immune system to identify and neutralize foreign objects such as bacteria and viruses.
Detailed explanation-5: -Binds to pathogens. Activates the immune system in case of bacterial pathogens. Directly attacks viral pathogens. Assists in phagocytosis. Antibody provides long-term protection against pathogens because it persists for years after the presence of the antigen. More items
