It seemed like a fairly straightforward query, so we tried a straightforward approach and typed "number cells human body." Our results were numerous and informative, but after flipping through them, we learned there really is no consensus on the answer.
Some sources told us that the average adult human body is made up of "50 million million" (50 trillion) cells, while others put the figure closer to 10 trillion. Science NetLinks, a resource for science teachers, stated that there are approximately "ten to the 14th power" (that's 100 trillion) cells in the human body.
Keep in mind, all of these figures are just estimates. At this time, there really is no way to know the exact number of cells in a human body. Can you imagine trying to count them all? Plus, as one source pointed out, the number will vary from person to person, depending on their size. The number of cells in your own body is constantly changing, as cells die or are destroyed and new ones are formed. So even the number of cells in your own body is not static.

6 x 10^12 cells are present in human body out of which 5 x 10^9 cells are replaced daily by our body.

We have about 100 trilion human cells (100000000000000). Guess what? We have upwards to 10 times that many (1 quadrilion) bacterial cells in and on our bodies. So if you add them all up, humans represent superorganisms of about 1.1 quadrilion cells in total.
Crazy, huh?
