Question

Is it true that a average human has 100 trillion cells?

Answer 1

No, it isn't. All humans have far, far less than that.

Answer 2

Ok. Thanks

Answer 3

Maybe it was 1 trillion cells

Answer 4

It was probably more like 200 billion cells.

Answer 5

There are all sorts of different estimates throughout the scientific/medical world. However, most sources will agree that it is between 10 and 100 trillion. Yes, this is a very vague number, but it isn't easy to narrow down numbers that are already in the trillions.

Blue, I don't think I've ever seen any sources that number it in the millions. Do you remember where you got that from?

Answer 6

"About 200 billion) comes from my textbook in "Intro Cell Physiology." Where do your numbers come from, biophil?

Answer 7

The Encyclopedia Britannica, a book called The Human Body we looked at in my physiology class, and also there are tons of sources online if you search for it, and I couldn't find one that numbered in the billions.

Even Nobel Prize.org had press release from one of the Nobel Prize winners in Physiology/Medicine, Leland H. Hartwell, numbers it at about 68 trillion.

Answer 8

Also, I wasn't trying to call you out or anything, I was just curious where it came from because I had never seen such low numbers before.
