Question

how many cells are there in human body​

Answer 1

The short answer is that the body of an average man contains around 30 to 40 trillion cells. The long answer is that scientists do not yet know the exact number. Plus, it depends on whether or not you include the bacteria that are present in and on our bodies.

The majority of the cells in our bodies are actually red blood cells. Although they make up over 80 percent of our body in number, they constitute only around 4 percent of total body mass. This is because red blood cells only measure on average 8 micrometers in diameter, which is 10 times smaller in diameter than an average human hair.

In contrast, the average size of a fat cell is 100 micrometers. Although fat cells make up nearly 19 percent of body mass, they contribute under 0.2 percent to the total cell number.

But why is it so difficult to figure out the exact number of cells in the body?

scientists concluded that the average human body contains approximately 37.2 trillions cells.
