We'll make it short and sweet for you to understand easily, because our immune system is a complex network of cells and proteins.
The simplest immune system definition is that it's a host of our body's defense mechanism to resist infections, that identifies a threat and neutralizes it.
These set of tissues work together to determine healthy cells from foreign organisms, or disease agents (viruses, bacteria and parasites - also known as pathogens).
Once the immune system detects these "intruders", it develops antibodies to fight them back, and remembers them!
Woo-hoo, way to go, our little armies! :-)
After you read this, you will NEVER take your immune system for granted! Here's why.
Immune System Parts / Immune System Diagram
The main immune system parts comprise of the white blood cells, antibodies, the complement system (proteins complementing the antibodies), and the lymphatic organs of the immune system.
The lymph system consists of the primary organs such as the thymus and bone marrow, and the secondaries like spleen, tonsils, auxiliary lymph vessels and nodes, Peyer's patch (in the intestines), adenoids (near the tonsils), skin and liver.

You can be at peace that your body's immune system is at a healthy level. But in reality, it's not a perfect world.
When we feel tired and achy, our immune system is technically telling us that it is busy fighting infection. But weak immune system diseases like pneumonia, ear or sinus infections, organ inflammation, blood disorders, should be alarming. Other signs of weak immune system are too much stress, recurrent fatigue and cold, slow healing of wounds and troubling tummy issues.
