Microbiome on skin
The human microbiome is the gathering of microorganisms which live on us. They live on the skin, in the spit and mouth, in the eyes and in the gut and whatever is left of the gastrointestinal tract. They incorporate microbes, organisms and single celled eukaryotes. The human has around 100 trillion cells, and conveys around tenfold the number of life forms in the digestion tracts alone.
