Carbon dioxide (CO2) is not poisonous because it does not bind to hemoglobin. Instead, it is carried in the blood as bicarbonate ions. CO2 is produced by the body as a waste product of cellular respiration. It is then exhaled through the lungs.
Here are some additional details about carbon monoxide and carbon dioxide:
* Carbon monoxide is a colorless, odorless gas. This makes it difficult to detect, which can lead to accidental poisoning.
* Carbon monoxide is produced by the incomplete combustion of fuels, such as gasoline, natural gas, and wood. It is also found in cigarette smoke.
* Carbon dioxide is a colorless, odorless gas. It is also heavier than air, so it can collect in low-lying areas.
* Carbon dioxide is produced by the body as a waste product of cellular respiration. It is also produced by the burning of fossil fuels.
Carbon monoxide is a dangerous gas that can cause serious health problems. It is important to be aware of the sources of carbon monoxide and to take precautions to avoid exposure.
