Question

Statement 1 - If any harmful bacteria enters our body, antigens and antibody acts on them and destroys them.
Statement 2 - More than $90\%$ of our body are bacterial cells and most of them are good guys.
Does that mean that antigens and antibodies are bacterial cells?

Answer 1

However, bacterial cells are found everywhere, throughout the body. They can be found on the skin, in the inner lining of our mouths, or the oesophagus. Furthermore, bacterial cells are also found in the intestines, and aid in digestion. Hence, antigens and antibodies are not part of the bacterial cells.
