immunology
Definition
Immunology is the study of how the body fights disease. It is a branch of biology that deals with the immune system, which is the body's defence system against germs.
The immune system is made up of many different parts, including white blood cells, antibodies, and proteins. These parts work together to fight germs and keep us healthy.
When germs enter the body, the immune system recognises them as foreign and attacks them. This can cause symptoms like fever, rash, and cough.
The immune system also remembers germs that it has fought before. This is why we don't get sick from the same germs over and over again.

Different forms of the word

Etymology
The word "immunology" comes from the Greek words "immunis" and "logos".
"Immunis" means "exempt" or "free from".
"Logos" means "study of".
So, the word "immunology" literally means "the study of what is exempt from". This is a very accurate description of the field of immunology, as it is the study of how the immune system protects the body from disease.
