Etymology

The term "Immune System Disorders" is derived from the Latin word "immunis", meaning "exempt", and the Greek word "systēma", meaning "whole compounded of several parts or members". The term "disorder" comes from the Old French "desordre", meaning "lack of order".

Types of Immune System Disorders

Immunodeficiency Disorders

Immunodeficiency Disorders are conditions in which the immune system's ability to fight off infections and diseases is compromised or entirely absent.

Autoimmune Disorders

Autoimmune Disorders occur when the immune system mistakenly attacks the body's own cells, tissues, and organs.
