      That’s a great question! I don’t really know the exact answer, but some people put the estimate at anywhere between 10 and 100 trillion cells, so quite a few 🙂

      Hi spursboy118 🙂 There’s absolutely loads – more than we could comprehend. Because cells are so tiny and there are so many it’s hard to say exactly how many there are. 50 trillion roughly 🙂
