In our body, antibodies are formed against pathogens in the thymus by lymphocytes. The thymus is an organ located in the upper chest, behind the sternum, and is an important part of the immune system. Lymphocytes are the white blood cells responsible for producing antibodies, which are proteins that help the body fight off and destroy harmful pathogens like bacteria and viruses. The thymus plays a crucial role in the development and maturation of lymphocytes, specifically T-cells, which are a type of lymphocyte involved in cell-mediated immunity. The antibodies produced in the thymus then circulate in the blood and help to protect the body from various infections. It is important to note that antibodies can be produced in other lymphoid organs like the spleen and lymph nodes as well.
