Human Body’s Little Heroes in Action in Microscopic Images
No fort can be defended without brave and trained soldiers; soldiers who must be prepared to give it all no matter how small their numbers or how big the enemy’s numbers. Our immune system is no different when it comes to defending our bodies. An amazing protection mechanism, our immune system is designed to defend us against millions of bacteria, microbes, viruses, toxins and parasites.
“War means fighting, and fighting means killing.”
– Nathan Bedford Forrest
To understand how important and effective our immune system is, all we need to see is what happens to bodies when something dies. With the body dead, the immune system also shuts down and in a matter of hours, the body is invaded by all sorts of bacteria, microbes and parasites. It only takes them a few weeks to completely dismantle the body until all that’s left is the skeleton! Our immune system makes sure that none of this happens while we are alive.
Our immune system’s defense begins with physical barriers such as skin and saliva. However, even if the germ crosses these barriers, it has to deal with a host of other soldiers – white blood cells, antibodies, macrophages, spleen, T-cells, lymph system and many others. To see how they deal with and destroy germs within our body, here’s a little pictorial walkthrough that’ll give movies like Troy and Matrix a run for their money!
