Question

Why co is poisonous

Answer 1

hi mate,

because it displaces oxygen in the blood and deprives the heart, brain, and other vital organs of oxygen. Large amounts of CO can overcome you in minutes without warning—causing you to lose consciousness and suffocate. ... Also, COpoisoning poses a special risk to fetuses.

Answer 2

because when we inhale CO it gets into our bloodstream and the hemoglobin in our body is more reactive towards CO and prefers CO over oxygen.
when this CO gets into our blood stream the hemoglobin attaches itself to the CO molecules instead of the oxygen molecules and travels the bloodstream carrying this CO throughout our body leaving oxygen behind....this leads to the body not getting oxygen for for it's cells and our body starts to slowly suffocate and die due to lack of oxygen.
