Unseen Work of the Immune System

The Immune System

The immune system is an amazing part of our bodies. Without it, humans would have long since passed from this planet. The immune system does thousands of things that benefit us throughout our life. Let’s take a look at the things that the immune system does and exactly how they work.

What Is The Immune System?

The immune system is a group of mechanisms in your body that guards and fights against diseases. These mechanisms first recognize disease-causing pathogens, tumor cells, viruses, and parasitic worms and then act to destroy them These mechanisms not only recognize these harmful bodies but also your body’s own healthy cells and tissues. The multi-tasking abilities of the immune system are what make it an incredible part of the body.

The Basic Ways In Which Your Immune System Works

Although the immune system does several things at once inside the body, its actions are really very basic. There are three main things that the immune system does. First, it acts a shield that keeps bacteria and viruses away from the body. Second, it identifies germs that were able to get in the body and destroys them before they start to embed themselves in the body and proliferate. Finally, the immune system finds every way it can to get rid of viruses or bacteria that have embedded itself in the body and reproduced.

The Immune System Works Around The Clock

Everyday you are actually exposed to several factors that harm your body. When you commute or step out of your house you breath in thousands of airborne germs that can cause you to catch a cold or flu. Your immune system fights these or prevents them from happening in the first place. Your immune system can also be disguised as allergies. Many times, your immune system will manifest physically, like when you get red bumps from mosquito bites or when you sneeze. Finally, it can help your body heal properly and protect it from infection whenever you get cut.

The Immune System And Serious Illnesses

Anyone can have cancerous cells. Cancer is actually the result of normal cells changing abnormally or reproducing out of control. In a number of cases, the immune system is able to detect and eliminate cancer in its early stages.

The Immune System Is Always Preparing Itself

When pathogens have been eliminated, the job of the immune system doesn’t stop there. Probably one of the most amazing things about the immune system is that it has the ability to keep record of all the pathogens and other harmful bodies it has eliminated before. The immune system has memory cells that “remember” every pathogen that it has encountered and destroyed before, so that when that specific type of pathogen appears again, the memory cells makes the body immune to harm and infection.

As you can see, the immune system is one of the most important elements of human survival. This is why everyone should take care of it and find ways to strengthen it.
