What do antibodies to do the body?

Answer 1

antibodies are proteins that stick to the invading microorganisms the antibodies lock onto the antigen and force the bacteria or viruses to clump together.

Answer 2

An antibody is a protein that your body produces which binds to the surface of a foreign body, like a bacteria or virus, and prevents it from actively damaging your body. Antibodies, generally bind other proteins, and they will bind to specific portions of the proteins. Antibodies have a number of functions, they can directly kill the invader, or they can recruit cell to the infection.

Different antibodies work on different substances; this is why you need immunizations, so your body knows which antibodies to make for those diseases. They're very specific, and viruses are changing all the time, which is why when you become immune to a cold one week you might get sick again a few months later - the cold has changed and your old antibodies no longer work on the virus packets.

Your body produces a whole bunch of antibodies for pretty much every type of foreign body that your immune system encounters and recognizes as an intruder. Some items are not recognized as intruders; titanium is one of these substances that your body will not react to, and so it's commonly used these days for medical implantation (for things like bone screws to hold a bone together).

Answer 3

Antibodies contribute to immunity by preventing pathogens from entering or damaging cells by binding to them; they stimulate removal of pathogens by macrophages and other cells by coating the pathogen; and they trigger destruction of pathogens by stimulating other immune responses such as the complement pathway.

Answer 4

Function of Antibodies is to fight against the antigens to protect the body

Answer 5

Antibodies stick to the antigen that are invaded and neutralises it.
