An example of this principle is found in immune-compromised people, including those with genetic immune disorders, immune-debilitating infections like HIV, and even pregnant women, who are susceptible to a range of microbes that typically do not cause infection in healthy individuals. The white blood cells are a key component. Later, we will explain how this works, but first, we will introduce some of the main characters in the immune system.White blood cells are also called leukocytes. If the pathogen manages to dodge the innate immune system, adaptive or acquired immunity kicks in.This protect from pathogens develops as we go through life.
National Library of Medicine: "How does the immune system work? As we are exposed to diseases or get vaccinated, we build up a library of antibodies to different pathogens. The immune system defends our body against invaders, such as viruses, bacteria, and foreign bodies.

Dead and faulty cells are also recognized and cleared away by the immune system.If the immune system encounters a pathogen, for instance, a bacterium, virus, or parasite, it mounts a so-called immune response.
"National Institute of Allergy and Infectious Diseases: "Immune System. Itâs made up of tissues, cells, and organs, including:All of these help create or store cells that work around the clock to keep your whole body healthy.Youâre born with a certain level of protection, or âimmunity.â But it can get better.Think of a baby or young child who comes down with colds, earaches, or other everyday illnesses often and babies who are breast feed continue to get antibodies from their mother while they are making their own.. Their immune system is creating a "bank"of antibodies as they are exposed to illnesses for the first time, enabling them to fight off future invaders. Your immune system can become less effective as you get older. That can make you more likely to get sick or get infections. "CDC: "Immunity types,""Vaccines and immunizations"and "Alcohol and public health. Overview of the Immune System.
The main function of the immune system is to protect the human body against disease and other foreign bodies. Antibodies are special proteins that lock on to specific antigens.Each B cell makes one specific antibody. MNT is the registered trade mark of Healthline Media.
When the lymph nodes detect antigens in the lymph, B-cell lymphocytes become activated to create antibodies specific to the offending antigen.
All rights reserved. Initially, a range of cell types works together to recognize the antigen as an invader.Once B lymphocytes spot the antigen, they begin to secrete antibodies (antigen is short for “antibody generators”). The immune system can be broadly sorted into categories: innate immunity and adaptive immunity.Innate immunity is the immune system you're born with, and mainly consists of barriers on and in the body that keep foreign threats out, according to the National Library of Medicine (NLM). Human immune systems, similarly to those of many animals, will attack foreign invaders from day one. The human immune system is a complex system that can identify threats to human health, distinguish these threats from the body’s own healthy tissues and eradicate these threats to keep humans healthy.
When you understand everything that it does for you, and how everyday things affect it, you can help it keep you well.Your immune system works to root out germs and other invaders that have no business in your body.For example, if you inhale a cold virus through your nose, your immune system targets that virus and either stops it in its tracks or primes you to recover.
