‘Why You Are Still Alive”, A Simple Explanation of How the Human Immune System Works

The Munich-based collective KurzGesagt (“in a nutshell”) gives a simple and very understandable explanation of the immune system at work in their animated video “Why You Are Still Alive – The Immune System Explained“.

Every second of your life you are under attack. Bacteria, viruses, spores and more living stuff wants to enter your body and use its resources for itself. The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome.
