Your Immune System


Your Immune System

What exactly is the immune system? Your immune system is an unsung superhero; It’s on the clock 24/7, protecting you from disease.  Every day, it fights off thousands of potentially deadly attacks from bacteria, viruses, parasites and fungi. And if it weren’t for the times when you are sick, you probably wouldn’t even realize that your immune system exists.

Understanding Your Immune System

So, what is this remarkable system and how does it work?  Your immune-systemimmune system is made up of special network of tissues, lymphatic organs and germ-fighting cells. A common way to understand this complex system is to think of your body as a castle; a fortress with different types of defenses to protect itself from foreign intruders, i.e. pathogens. There are three lines of defense: The first includes your skin, stomach acids, mucous membranes and tears.

If an intruder manages to get through this first line of defense via food, your nose or a cut, a second line of defense, called inflammation, automatically kicks in. And as soon as this happens, the third line of defense, immune cells, are called into action. Immune cells are large amounts of different types of white blood that are made in the bone marrow. When called into service, these special cells work together to seek out and destroy pathogens.

And as if this weren’t enough, if you’re re-exposed to a specific pathogen, your immune system can remember it, and quickly identify and destroy it before you get sick.  When this happens, your body has become “immune” to the disease.
