What Is Carbon Monoxide Poisoning? What Causes Carbon Monoxide Poisoning?

Carbon monoxide has no smell or taste; it is a byproduct of combustion. Humans and other animals with lungs cannot tell when they are breathing in carbon monoxide. Carbon monoxide competes with oxygen for binding sites on hemoglobin. Hemoglobin is the molecule in red blood cells that carries oxygen from our lungs to tissues all over our body, and returns carbon dioxide from the tissues.http://feedads.g.doubleclick.net/~a/...Ewl77kFP0/0/di
