What is the effect of carbon monoxide in the blood?

Question

I think its because carbon monoxide combines with the blood to form carbooxyhaemoglobin which reduces the amount of oxygen combining with haemogloblin.Hence a person suffers from lack of oxygen and consequently may die from suffocation.Am I right?

Answer 1

almost. Carbon monoxide combines with hemoglobin to form carboxyhemoglobin, which prevent oxygen from binding to the hemoglobin.

Answer 2

Yes you are right
