Happy Pi Day! π ♥
I made a video for my immunology class! Watch and maybe learn something :)
As I've said before, I love crafts+science.
Some background: Macrophages are one of the early defenders against infection in your body. They phagocytose (or eat up) bacteria and pathogens that they find, like if you get a cut. When the macrophage realize that your body is harboring foreign fugitives, it does its best to sound the alarm to the rest of your immune system by producing inflammatory cytokines.
