Cells In The Human Immune System.

The human immune system is not made up of different major organs, instead, it is made up of different kinds of immune cells. First, in the body there are many white blood cells, called Lymphocytes. When a perticular pathogen enters your system the immune system is notified by its antigens. This is where the Lymphocytes come in. When the immune system is aware of an intruder, the white blood cells react by releasing antibiodies, which are "Y" shaped tolls designed to immobilize the intruding pathogen until other cells can break them down.
