Chapter 3.2 Introduction
The Immune System pg. 100

The immine system is a system in which it defeats unwanted bacteria making your immune system even stronger. For example, pathogens create infectious diseases, so the immune system attacks and destroys the pathogens as well as antigens that enter the body. There are two lines of defence. The first like is the skin and its linings of the bosy's internal systems. Then, the second one is that innate/built in responses are quick while an aquired response is slower and more specific. Immune systems make specific antibodies that attach to antigens and destroy them. This involves B cells, helper T cells, killer T cells, and memory B cells. Over all, your immune system's main funtion is to attack and destroy unwanted bacteria or cells in your body.
