Carbon monoxide combines with haemoglobin to form carboxyhaemaoglobin. Haemoglobin carries oxygen to tissues ( as oxyhaemoglobin) and this vital function is interrupted when carbon monoxide is bound to haemoglobin instead of oxygen. Death can be the result.

Hello Arnaldo,


Carbon monoxide bonds to the red blood cells, particularly to an iron ion present in a protein called haemoglobin. This bonding prevents the red blood cells from attaching to oxygen, which would make our cells unable to respire and work. Does this make sense?
