I just finished my lecture weekends on the Immune system. I thought Digestion was complicated (Its Just One Bite of Food). I thought Biochemistry was mind-blowing. I was amazed at the Liver and all the things it does for us.
However, the immune system is on another level.
Let me give you an example. We have 2 types of immunity in our bodies.
We have “Innate” immunity which we are all born with and provides us with a universal defense mechanism against infection and invading pathogens (the bad guys – viruses, bad bacteria, toxins, parasites). It works in a non-specific way in that it looks for and kills anything that looks even remotely suspect floating around inside of us. This is a super important defense mechanism as when we are born this is the ONLY defense we have for the first 4-7 days of life. Incredible right?
After 4-7 days, a second type of immunity is born.
