Do we exhale carbon monoxide?

As humans, we breathe in oxygen and exhale carbon dioxide. However, some people out there believe that we also exhale carbon monoxide. Is there any truth to this claim? In this article, we will take a closer look at the science behind respiration and whether or not it’s possible for us to be breathing out such a deadly gas.

The basics of respiration

Before delving into the question at hand, let’s first understand how our bodies actually go about breathing. When we inhale (which you’re probably doing right now), air travels through our nose or mouth down our trachea and eventually reaches our lungs where oxygen is extracted from the air by tiny air sacs called alveoli. Oxygen then binds with hemoglobin in red blood cells and is carried throughout our body to fuel various cellular processes.

Once these processes have used up all the oxygen they need, they create waste products that must be removed from the body – one of which being carbon dioxide (CO2). Carbon dioxide molecules are transported back to the lungs via blood vessels and then exhaled during expiration.

But what about carbon monoxide?

So where does carbon monoxide come into play? Well , as you may already know if you’ve ever taken a health class or watched an episode of House M.D., CO{}2 isn’t the only gas present in cigarette smoke. One of those other gases happens to be CO – which just so happens to bind more strongly than oxygen with hemoglobin inside your red blood cells !

Carbon monoxide exposure can lead to headaches, dizziness, nausea – painful symptoms indeed ! It prevents your body from receiving enough needed oxygen – simple but extremely dangerous hyper-short circuiting on a molecular level right within your veins . And because its binding affinity with hemoglobin is much stronger than that of O2, inhaling high concentrations of CO can lead to suffocation and death.

Do humans exhale carbon monoxide, though?

Well, the answer is no – but it’s not as simple as that. While we don’t actively produce carbon monoxide when we breathe, our bodies do contain small amounts of this toxic gas that are produced through natural metabolic processes such as digestion – so you basically have a tiny bit of poisoning going on inside you at all times . But despite what some people may claim (or seem to insinuate when they see someone smoking), the amount of CO being exhaled by human breath is negligible compared to other sources like vehicle exhaust fumes or industrial pollution.

Beside endogenous production: Smoking tobacco (which could cause lung cancer! So quit already) also releases significant quantities of CO into the air around us. Passive inhalation second hand smoke can put non-smokers at risk for exposure effects since your hemoglobin begins stealing it in favor over oxygen molecules – this leads to potentially fatal consequences especially if you’re indoors with limited ventilation options !

Don’t confuse ’em!

With all these facts in mind, it’s important not to get carbon dioxide and carbon monoxide confused. They’re two very different gases with different roles in respiration – one being important for keeping us alive and healthy while the other poses serious health risks even in minute quantities – yes even more than chlorine gas which could pretty much dissolve everything involved its path! (Joking aside stay clear from both without proper protective equipment!)

So next time someone tries claiming that humans exhale deadly levels of carbon monoxide, feel free to set them straight. Not only will you be correcting their medical ignorance but possibly saving someone else from getting scammed or believing an outright lie !
