Immunology: What is Immunology

What is Immunology? Immunology is the study of your immune system—the complex network of cells, organs, and tissues that work together to protect you from infectious diseases and other threats. Introduction Immunology has its origins in the study of how the body protects itself against infectious diseases caused by microorganisms, such as bacteria, viruses, protozoa, and fungi, and also parasitic organisms, such as helminth worms. Important initial barriers to infection are physical (e.g. the skin), enhanced by substances secreted by the body, such as saliva and tears, that contain molecules that can neutralise bacteria. The internal mucosal tissues (e.g. lungs & airways, and the ... Immunology is the study of immune systems in all organisms, their functions, disorders, and applications. Learn about the history, classification, components, and tests of immunology, as well as its relevance to medicine and biotechnology. Immunology is a rapidly advancing field with many specialized areas of study. The complexity with which the immune system combats infection rivals the complexity of the numerous types of microbes that can cause disease. This article does not aim to provide an in-depth review of immunology.
