Explain why, it is dangerous to inhale air containing carbon monoxide.

Inhalation of carbon monoxide is dangerous because Carbon monoxide combines with hemoglobin and forms carboxyhemoglobin. This carboxyhemoglobin replaces oxygen. Then blood faces the shortage of oxygen. Due to the lack of oxygen, the person will face difficulty in breathing. The person may also die due to this lack of oxygen. So it is dangerous to inhale air containing carbon monoxide.
