Detailed explanation-1: -drumroll … 37.2 trillion cells. This is not a final number, but it’s a very good start. While it’s true that people may vary in size–and thus vary in their number of cells–adult humans don’t vary by orders of magnitude except in the movies.

Detailed explanation-2: -Every one of the 37 trillion-or-so cells in your body is unique to some extent. Types of cell are determined by the particular proteins they contain – so only a red blood cell has haemoglobin, for example, and a neuron contains different proteins from an immune cell.

Detailed explanation-3: -There are about 100 trillion cells that make up the human body. A new megascience endeavor will catalog and image each of the 200 or more types of cells from the 80 known organs and identify the genes that are active in these cells.

Detailed explanation-4: -Background of research Our bodies are made up of no less than 60 trillion cells. Cell division is an essential process for building our body from only a single fertilized egg. The abnormal cell division is also known to cause severe diseases such as cancer.

Detailed explanation-5: -In other words: The human body consists of some 37.2 trillion cells. For a long time, scientific estimates of the number of cells in the human body ranged between 1012 and 1016.
