The immune system is a network of biological processes that protects an organism from diseases.
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.

Type a minimum of three characters then press UP or DOWN on the keyboard to navigate the autocompleted search results. The immune system keeps a record of every microbe it has ever defeated, in types of white blood cells B- and T-lymphocytes known as memory cells. This means it can recognise and destroy the microbe quickly if it enters the body again, before it can multiply and make you feel sick. Some infections, like the flu and the common cold, have to be fought many times because so many different viruses or strains of the same type of virus can cause these illnesses.
What is immunology?
NCBI Bookshelf. Last Update: July 30, ; Next update: Our immune system is made up of both individual cells and proteins as well as entire organs and organ systems. The organs of the immune system include skin and mucous membranes, and the organs of the lymphatic system too. Your skin and mucous membranes are the first line of defense against germs entering from outside the body. They act as a physical barrier with support from the following:. Bone marrow is a sponge-like tissue found inside the bones.
Synopsis: In this lecture we will discuss the cells and. 1ssues of the immune system and the roles they play in innate and adap1ve immune responses.
Immune System: Diseases, Disorders & Function
The immune system includes primary lymphoid organs, secondary lymphatic tissues and various cells in the innate and adaptive immune systems. The key primary lymphoid organs of the immune system include the thymus and bone marrow, as well as secondary lymphatic tissues including spleen, tonsils, lymph vessels, lymph nodes, adenoids, skin, and liver. The thymus is largest and most active during the neonatal and pre-adolescent periods of development.
Our immune system is essential for our survival. Without an immune system, our bodies would be open to attack from bacteria, viruses, parasites, and more. It is our immune system that keeps us healthy as we drift through a sea of pathogens.
The immune system is composed of a variety of different cell types and proteins. The immune system is a wonderful collaboration between cells and proteins that work together to provide defense against infection. These cells and proteins do not form a single organ like the heart or liver. Instead, the immune system is dispersed throughout the body to provide rapid responses to infection Figure 1. Cells travel through the bloodstream or in specialized vessels called lymphatics.
