How many organism are in the human body?

Answer 1

To answer this question, we have to ask ourselves the question, what is an organ? An organ is a complex structure made up of 2 or more different tissue types. Examples of organs include the skin, each muscle, each bone, a lymph node, a blood vessel, a nerve, the sense organs, etc. Given that there are over 700 muscles in the body and that there are on average 206 bones, there would be well over 1 organ in the body if you include all of the internal organs.

Answer 2

You body is free of microbes inside. That would be inside the cavity that contains the heart, lungs and the outside of the intestines and outside of the reproductive organs. The layers under your skin are germ free. The muscles, bones, blood vessels, heart, brain, spinal cord and nerves are microbe free. All their connective tissues as well.
But every part of your body that has an outside connection is not. That would be the respiratory tract (nose, trachea and lungs). That would include the mouth, inside the stomach, intestines and to the anus. That entire tract is really outside of your body. The same is true for the reproductive organs. The opening and the areas that lead to them can have microbes. And the skin is covered with microbes as well. There are probably trillions of them on the skin alone.
