How the human immune system works

The antigen-antibody reaction forms the basis for this immunity. When an antigen (antibody generator)-such as a harmful bacterium, virus,. Inside your body there is an amazing protectio­n mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body.

A short answer is that the immune system works by a)recognizing invading substances as foreign, and b) activating cells and processes which neutralize the foreign substance.

You have specialized blood cells which help in this process. What are the key components of the human immune system? How can we improve the immune system? How does your immunity system work? Find out how the human immune system works.

When functioning properly, the immune system identifies and attacks a variety of threats. It is made up of different organs, cells and proteins.

Aside from the nervous system, it is the most complex system in the human body. Understanding the Immune System How It Works U. In some cases medications are prescribed to treat conditions that directly compromise the immune system or when the immune system is lacking important components. For example, some people are born with a condition called agammaglobulinemia. This condition causes a problem with a person’s B cells, so they do not produce antibodies. Of all the cells involved in the immune system, are plasma.

This is the non-cellular part of our blood. Plasma is what you’re left with when you remove the red and white blood cells. So, those cells make up the remaining of our immune system response. The white blood cells are a key component. Here, we explain how it works , and the cells, organs.

Over hundreds of millions of years, the adaptive immune system has evolved an elegant solution to keeping people healthy. Learn more about how the genetic diversity of the human adaptive immune system gives us the ability to detect and respond to millions of disease specific antigens. The human immune system is divided into two broad groups called the Acquired Immune System and the Innate Immune System. The details about these two systems and how they work is dealt with more under their specific pages.

This page will deal more with the structures of the immune system , detailing the parts of the body that play a role in.
