So we conclude that although our body actually does produce a very tiny amount of carbon monoxide, and carbon monoxide does have a certain beneficial effect in our body, because our body naturally produces such a small quantity of hemoglobin, our blood contains about 0 mercury of carbon monoxide. That means our carbon monoxide or natural levels of carbon monoxide inside our blood plasma have no adverse effects on hemoglobin. However, other processes that take place outside of our body, for example, the production of car exhaust or the process of smoking these processes produce much more carbon monoxide. And if we are exposed to even a small amount of carbon monoxide that comes from these processes, it can ultimately lead to the condition of carbon monoxide poisoning. Now, how exactly would one treat carbon monoxide poisoning? Well, recall that carbon monoxide and oxygen bind to the same exact location on hemoglobin, and they bind reversibly.
