      Your cells are very very small. This allows the human body to have approximately 10 trillion cells. This number looks like this if written out: 10,000,000,000,000 cells.

      But this is only your cells. Your body also has many good and bad bacteria inside it. Bacteria are even smaller than your cells, some are ten thousand times smaller. This means that you can have 10 times more bacteria cells in your body than your own cells!! This number is 100,000,000,000,000 possible bacteria cells in your body.

      I’m not even including how many bacteria might be on your skin, which could make the number even bigger!!!
