How does the immune system work

How does the immune system work, is a question that most people ask when they are sick. However, the immune system is always at work whether you are sick or not.

Your immune system is your body's natural ability to get over an illness or take care of harmful microorganisms that wish to invade your body. You would be surprised how many of these organisms want to invade your body every day, and your immune system works tirelessly around the clock ensuring you stay and feel healthy.

How does the immune system work within your body

The immune system is made up of many different cells, organs, tissues and substances within your body, which each play their own role in eliminating these foreign organisms and protecting you from various diseases and illnesses. These foreign organisms come in the form of viruses, bacteria, parasites and fungi. They are known as “microbes.”

The human body is the ideal environment for these microbes and so they try to break into your body and use its resources for their own ends. This is what makes you sick. Your immune system's job is to keep these organisms out or, if they have managed to get in, track them down and eliminate them. It's like your body's 'defense force' – each cell or organ playing its own part in eliminating the invading, foreign microorganism that wants to harm you.

How does the immune system work in cells

The cells in the immune system are known in layman's terms as the 'white blood cells' (the Leukocytes) and are different to your red blood cells (erythrocytes), which are responsible for carrying oxygen and carbon dioxide. The white blood cells are remarkable in many aspects, one of which is that some of these cells are capable of 'remembering' the millions of foreign organisms that have tried to invade your body in the past and are also capable of detecting a foreign organism early and easily. Some of these cells 'tag' the organism, while others work at producing secretions to wipe the organism out. As you can see the immune system work, each white blood cell also has it's own role in discovering and eliminating these invaders.

If we did not have an immune system, we would never get over the flu or even a minor cold and would end up dying due to the simplest of illnesses. Some people have such a strong immune system that they don't catch a cold or get sick at all in some cases. This doesn't mean that their bodies were not invaded by the bacteria or virus, only that their immune system was strong enough to defeat it

Two people can often be exposed to someone with the flu, and only one of them will 'catch' it and the other won't. It had everything to do with the immune system, not with who was lucky enough to avoid the flu and not contract the virus. Some people may catch the flu only much later when their immune system is weaker.

How does the immune system work against invaders

The immune system has a remarkable ability to be able to distinguish between what is your body's own cells (known as 'self') and what is foreign (known as 'nonself'.) Each cell in your body has a marker to distinguish it as 'self.' When a cell travels without this marker, or a foreign molecule is attached to the cell, the immune system immediately recognizes the invader as 'nonself' and gets to work.

You can see your immune system functioning through various every day occurrences. When you get cut, many kinds of viruses and bacteria invade your body through the cut in your skin. This is why it's a good idea to wash the wound, just to ensure that you can help the body out a bit. Your immune system gets to work immediately and destroys the foreign organisms that have invaded your body quickly and easily, while the skin heals and closes the cut. When an infection occurs, however, this is a clear sign that the immune system has missed something. The infection is usually inflamed or filled with pus, which is simply a side effect of the immune system.

You would also be surprised how many germs and bacteria you eat every day. Not to worry, many of the bacteria are actually good for you, and those that aren't, are killed in the saliva or stomach acid. Food poisoning only occurs when a germ gets through, and your body will work tirelessly to get rid of it from your system.

How does the immune system work with the environment

When you itch from being bit by a mesquito, this is a sign that your immune system was at work and pushed out the poison that was trying to invade your body. Another example is when you get a splinter, the skin pushes out the splinter and the immune system destroys any harmful organisms that tried to get in.

Allergies are also a clear sign of the immune system at work. However, allergies occur when the immune system is over-reacting or over-compensating for a foreign organism. This is why some people suffer more than others. You can see the immune system react in a very similar way during organ transplants when certain organs are rejected by the body. This is the immune system at work.

With all this in mind, it is easy to see why it's so important to know the answers to: how does the immune system work. There are a number of factors which can contribute to a weak immune system – and these factors are usually the LACK of doing regular things that help in boosting your immune system.

These regular things include eating the right foods that build your immune system.

Good nutrition is important for normal function of the immune system. Studies at both the University of Florida and the University of Arizona found that certain whole food supplements support several important markers of proper immune function.
