where are antibodies found
In total, there are five types of antibodies. Each type is found in a different part of the body and has a different set of duties. Each one of them is referred to by a letter following the abbreviation Ig for immunoglobulin. The most common antibody we have is the IgG antibody. IgG is found in all of the body's fluids. It makes up about 75-80% of all of our antibodies. These antibodies help to fight off bacteria and viruses. To go with the flow of the fluids, IgG antibodies are the smallest antibodies in size.
IgM antibodies are the largest antibody. They are found in blood and lymph fluid and are the first type of antibody made in response to an infection. They also cause other immune system cells to destroy foreign substances. IgM antibodies are about 5% to 10% of all the antibodies in the body.
