Hi imthemvp23!

I am actually really fascinated by something called the microbiome – it isn’t an organ but a collection of good bacteria that lives in our body all the time. I read somewhere that we have more bacteria in us than human cells! Without these bacteria, our bodies wouldn’t function properly – they help with jobs like digestion and disease prevention. Pretty cool!
