All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. The average adult human body has around 37.2 trillion cells. WOW, that's a lot of cells. So many, in fact, that it's hard to picture.
Going back over the last two centuries, the estimates for the number of cells in the human body have been in the trillions. How many trillions? Anywhere between five trillion, and 200 million trillion! An estimate that has a range between 200 million down to just five is perhaps a little too loose to be of any use.
