Carbon monoxide gas is more dangerous than carbon dioxide gas. Why?

Carbon dioxide (CO₂) and carbon monoxide (CO) gases are emitted during the combustion of various fuels. Carbon monoxide is poisonous, whereas carbon-dioxide is non-toxic in nature.
 
Carbon monoxide is poisonous because it is capable of forming a complex with haemoglobin (carboxyhaemoglobin), which is more stable than the oxygen-haemoglobin complex. The concentration range of 3–4% of carboxyhaemoglobin decreases the oxygen-carrying capacity of blood. This results in headaches, weak eyesight, nervousness, and cardiovascular disorders. A more increased concentration may even lead to death. Carbon dioxide is not poisonous. It proves harmful only at very high concentrations.

Carbon monoxide (CO) is more dangerous than carbon dioxide (CO₂) because CO can stop your blood from carrying oxygen.

It sticks to hemoglobin in your blood much stronger than oxygen does, so your body can’t get enough oxygen.

On the other hand, carbon dioxide is something your body naturally produces and can handle in small amounts.

That’s why breathing in CO is much more harmful and can quickly make you very sick or even cause death.

Carbon monoxide is more dangerous than carbon dioxide because it blocks oxygen from getting into your blood.

It binds to the blood’s hemoglobin way better than oxygen does, so your body doesn’t get the oxygen it needs.

Carbon dioxide is less harmful because your body can remove it naturally, but carbon monoxide can quickly cause serious harm or even death.

Carbon monoxide is more dangerous than carbon dioxide because it stops your blood from carrying oxygen by attaching to hemoglobin tightly.

This means your organs and tissues don’t get enough oxygen, which can be deadly.

Carbon dioxide, on the other hand, is less harmful since your body can get rid of it easily.

Carbon monoxide is more dangerous than carbon dioxide because it binds to your blood’s oxygen-carrying molecule much stronger than oxygen itself.

This prevents oxygen from reaching your body’s cells.

Carbon dioxide is less harmful because your body naturally gets rid of it when you breathe out.

That’s why carbon monoxide can be deadly even in small amounts.
