Respuesta :

Answer:

There are many harmful chemicals in the cigarette that increases the red blood count. The compounds that is found in the cigarette are carbon monoxide, and other compounds that decreases the level of oxygen inside the body.

In order to compensate the oxygen level of the body, the body boosts the level of production of red blood blood cells in the body.
