How does the Immune System Work?

How the immune system works

The immune system is like a machine that’s constantly in “ON” mode to protect the body against harmful infections (outside invaders). But just like every machine, it requires fuel to keep it running. Fuel for the immune system is an adequate supply of nutrients to keep ramping up it’s activity.

But, are you wondering how the immune system works and ultimately protects us from bacterial as well as viral infections? Our infographic will tell you how & covers the two most vital aspects in this regard:

  • Structure of Immune System
  • Function of Immune system


Importance of Immune System

To understand the importance of the immune system, imagine for once it ceased to exist or you had a weak one (didn’t work properly) ? What exactly would happen?

We don’t notice the immune system when our body is running smoothly, but the repercussions your body could have if it stopped working are very aggressive in nature whether it’s not being able to fight germs and having to deal with viruses and bacteria that you’ve never heard of before, that, in itself shows us the importance of immune system.

You will also notice that you tend to get more allergic reactions. This is because the immune system also keeps inflammation in check. When the same system that’s meant to protect you doesn’t react strongly enough, your body mistakes your healthy organs and cells for invaders and begins attacking them, leading to dangerous autoimmune diseases like Type 1 diabetes, arthritis, lupus and many more.

Some of the most crucial tasks of the immune system are :

  • To target & fight off infection and disease causing pathogens like fungi, viruses, bacteria etc, and eradicate them from the body
  • To identify and counteract any harmful outside invaders present in the environment
  • To fight any harmful disease causing changes such as cancer cells.

Furthermore, the immune system has two branches:

Innate Immunity- This branch provides general defence against common pathogens like bacteria, virus, or other microorganisms), another reason why it is also referred to as a non-specific immune system.

Adaptive Immunity- This branch of the immune system is more responsive in nature, as it targets any incoming threats by learning how to give off specific responses against any virus or bacteria that the body has already come into contact with earlier.

These branches, thus, work together to provide our body with exemplary protection.

Now, Imagine if all this Stopped? Scary isn’t it?
