It binds to hemoglobin, thus depriving cells of oxygen.

|
It enters cells and forms a barrier to oxygen.

Detailed explanation-1: -Exposure to carbon monoxide impedes the blood’s ability to carry oxygen to body tissues and vital organs. When carbon monoxide is inhaled, it combines with hemoglobin (an iron-protein component of red blood cells), producing carboxyhemoglobin (COHb), which greatly diminishes hemoglobin’s oxygen-carrying capacity.
Detailed explanation-2: -Carbon monoxide combines with hemoglobin to form carboxyhemoglobin at any or all of the oxygen-binding sites of hemoglobin, and also acts to increase the stability of the bond between hemoglobin and oxygen, reducing the ability of the hemoglobin molecule to release oxygen bound to other oxygen-binding sites.
Detailed explanation-3: -CO binds to hemoglobin with much greater affinity than oxygen, forming carboxyhemoglobin (COHb) and resulting in impaired oxygen transport and utilization. CO can also precipitate an inflammatory cascade that results in central nervous system (CNS) lipid peroxidation and delayed neurologic sequelae.
Detailed explanation-4: -The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO it can make you pass out or kill you.
