Say what the function of the immune system is
The function of the immune system is to protect the body against disease or potentially damaging foreign pathogens. It identifies a variety of threats, including viruses and bacteria and distinguishes them between their own self-cells. The immune system uses a variety of components to help fight the invading pathogens described in the table below. The immune system is divided into innate and specific immunity.
Identify the main components of the immune system and describe the roles of each of these components.

Describe how the immune system works in a healthy body.
A healthy immune system relates to all levels of defence working at its maximum ability. For example the first line of defence working at maximum level to stop invading pathogens from entering the body, the second line of defence where phagocytosis occurs where macrophages engulf pathogens and digest them and finally where the third level is working efficiently can target any specific antigens and have them neutralised.
