How Does the Immune System Protect the Body from Disease?

50 Free Resources to Understand the Power of the Immune System

The immune system helps protect our bodies against diseases caused by pathogens. Pathogens, including viruses, bacteria, and parasites, invade our bodies and cause infection and/or disease. The immune system's complex system of cells, tissues, and organs protects us against invaders by attacking them while leaving healthy tissue alone. Doctors and scientists continue to work to learn more about how our immune system protects us from disease, though they already know a great deal. For example, doctors and scientists know that the immune system is comprised of the innate system and immunity. The innate system includes the immune defenses we are born with, including skin, mucous membranes in our mouth and nose, gastric acid, and saliva. Immunity is the second line of defense that protects us against pathogens that make their way through the innate system. The immune system is housed in the blood as white blood cells or chemicals that are released by cells and tissues. Specialized white blood cells that aid in immunity are neutrophils, lymphocytes, eosinophils, monocytes, and basophils; they move throughout the bloodstream and protect against infection caused by pathogens. The immune system also helps encourage the growth of good bacteria in the gut. This good bacteria is particularly good at fighting off invaders in the intestinal tract. One study found that gut microbiota interacts with both the innate and immune systems; therefore, people take probiotics to increase the amount of good bacteria in their systems and boost their immune system so they can better fight infection and disease. Knowing how your immune system protects the body from disease helps you understand how to strengthen your immune system and the steps you can take to improve your health. To help you better understand the role the immune system plays in fighting disease, we have rounded up 50 top resources that are free of charge. The following articles, guides, videos, multimedia resources, and infographics explain the function of the immune system and offer a great deal of information from leading health organizations, research institutions, medical professionals, and other immune system experts. While we have included a Table of Contents to make it easier for you to find the resources of most interest to you, it is important to note that we have listed our 50 top resources for understanding how the immune system protects the body from disease in no particular order.

  • Vaccination helps the immune system respond earlier and more efficiently to antigens
45. How Does the Immune System Work @IOkidney  10-for-IO is a new global resource for kidney cancer patients and organizations that are interested in immune-oncology (IO). Their interactive article, How Does the Immune System Work, provides a thorough overview of the immune system and immune response, complete with a Q&A format that enables readers to learn exactly what they want to know about how the immune system protects the body from disease. Three key facts we like from How Does the Immune System Work:
  • Lymphocytes are the most specialized cells of the immune system; they are rare in the blood but they are important at the site of infection or cancers, where they identify the target the immune system must specifically destroy
  • Dendritic cells teach lymphocytes which cells are normal and which are invaders by aiding lymphocytes in the process of examining pieces of proteins from the surface of cells
  • When lymphocytes recognize an infected cell, they trigger the immune response to destroy disease-causing invaders or cancer cells
46. Immune System - Big Picture @wellcometrust  Wellcome Trust is a charitable foundation that exists to improve health for everyone. They offer Big Picture, a resource that is "bringing cutting-edge science into the classroom and beyond." Immune System is their interactive article that offers a detailed look into how this body system protects us from the organisms and substances that seek to do us harm. Three key facts we like from Immune System - Big Picture:
  • Diseases spread when the body's defensive barriers are breached
  • Antibody levels change during the immune response in an attempt to rid the body of disease-causing invaders
  • Thanks to antigen recognition, the immune response includes an antibody attack on antigens
Infographics 47. Diagram of the Human Immune System @LiveScience  LiveScience shares science news on a variety of topics, including health and the immune system. This infographic capture the immune response of a healthy body and illustrates the ways in which the immune system identifies and attacks threats to protect us from disease. Three key facts we like from Diagram of the Human Immune System:
  • Properly functioning immune systems identify and attack threats while leaving healthy tissue alone
  • Lymphocytes and leukocytes are key components in the fight to protect the body from disease; lymphocytes destroy bacteria and toxins or infected or cancerous cells, and leukocytes identify and eliminate pathogens
  • The lymphatic system includes bone marrow, the spleen, the thymus, and lymph nodes and plays a crucial role in protecting the body from disease
48. Immune Function @nationwidekids  Nationwide Children's Hospital is America's largest pediatric hospital and an international leader in research. Their Immune Function infographic illustrates the two sides of the immune system: the innate immune system and the adaptive immune system. Three key facts we like from Immune Function:
  • Macrophages engulf the pathogens and kills them as part of the innate immune system
  • The immune system recruits phagocytes, such as monocytes and neutrophils, to fight foreign pathogens that enter the body
  • The adaptive immune system switches on when the body detects a specific antigen; otherwise, it stays inactive because the monocytes are not displaying pieces of a specific antigen on their cell surface
49. Immunology: Immune Response @geekymedics  Billed as a "fun medical revision platform for medics, by medics," Geeky Medics is a resource for medical students who want to learn more productively. Immunology: Immune Response features several infographics, diagrams, and other visual aids to demonstrate how the immune system protects the body from disease. Three key facts we like from Immunology: Immune Response:
  • While the immune system itself is a mobile, circulating system, some fixed anatomical structures, such as bone marrow, the thymus gland, lymph nodes, the spleen, and the liver, aid in its function
  • The cells of the immune system include granulocytes, monocytes, and lymphocytes
  • Normal immune response includes four main components: pathogen recognition, acute inflammatory response, antigen presentation with activation of specific T helper cells, and a target antigen-specific immune response coordinated by CD4 helper T cells
50. The Specific Immune Response - When the Body Declares War!   From the Government of Western Australia, The Specific Immune Response - When the Body Declares War! is features an interactive diagram and infographic that thoroughly explain the seven steps of the body's specific immune response to a non-self antigen, such as a virus. Three key facts we like from The Specific Immune Response - When the Body Declares War!:
  • B cells activate and produce an antibody-mediated response when a virus enters the body, multiplies, and invades the cells
  • Antibodies combine with specific antigens and destroy them
  • Suppressor t cells stop the immune response

Flu, cough, and colds best treatment is your own active immune system. Help it with plenty of fluids, nutrition, rest, exercise and hand washing.
