  • Published: 01 July 2014
  • 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. An animation of the immune system.

        At 4:47, the term 'plasma cells' is used first time without specifying that a plasma cell is effector/ activated B cell. Just an observation. Very informative video. Thanks.

                While we are amazed how these cells work just to protect us, why aren't we wondering who made these complicated system? Don't tell me it's just a product of chances that took place a million years ago. It's impossible for that without supreme Creator engineered and designed it.
