Antibodies… what are they? Antibodies are proteins in which circulate within out bloodstream. They are a huge part of our immune system, also commonly known as ‘immunoglobulins’. Antibodies are made up by a certain type of white blood cell’s called B lymphocytes. Antibodies attach themselves to proteins and various other chemicals within the body that are not commonly found (Foreign chemicals) these specific chemicals are also known as antigens. Antibodies help to protect us against bacteria, viruses and multiple other infections. Some germs actually have antigen proteins on their surface, the immune system is able to recognize these as foreign and so when infections strike the B lymphocytes create thousands of antibodies in which attach themselves to the germs, this has a very low chance of failing however should our bodies need that little extra nudge in the right direction B lymphocytes can also attract other parts of the immune system e.g.- White blood cells in which have the ability to destroy the germ.
