Not only does the hemoglobin prefer CO, it holds on to the CO much more tightly, forming a complex called carboxyhemoglobin (COHb).

What gas blocks oxygen from combing with hemoglobin in the lungs?
carbon monoxide (CO)
What is the effect carbon monoxide in human lungs?
The harmful effects of carbon monoxide (CO) does not manifest itself in the lungs. Rather CO acts as a gas similar to oxygen, it diffuses through the lungs tissue as normal and binds to hemoglobin, which is normally used to transport oxygen around the body by binding to it and carrying it around. However, this is where CO becomes harmful. CO enters the bloodstream and binds to hemoglobin with a far greater affinity that oxygen, in essence inactivating the hemoglobin molecule. Therefore hemoglobin is unable to properly transport oxygen since it is already bound up by CO and hypoxia sets in quickly. There is no way to "cure" CO poisoning in the way to chemically unbind CO from hemoglobin, this is why individuals with CO poisoning must be removed from the CO environment and given 100% oxygen to breath, to allow the slow process of CO dissociation from hemoglobin to occur.
What is the complex salts?
A complex salt is the salt of one or more complex ions, the complex part can be cationic or anionic or both such as Ca3[Co(Cl)6]2 the complex part behaves as an anion [Co(NH3)6]Cl3 the complex part behaves as a cation [Co(NH3)6][Co(Cl)6] the both of the anionic and cationic parts of the are formed by complex ions
What is the equation for carbon monoxide poisoning?
CO Carbon monoxide is combined with hemoglobin and carboxyhemoglobin is formed; this compound block the diffusion of oxygen in blood.
What gas found in cigarette smoke blocks the transport of oxygen by the hemoglobin in the blood?
CO (carbon monoxide). It binds to the same sites on hemoglobin that oxygen would, except with a much greater affinity than oxygen does. Think of hemoglobin as a bus transporting oxygen from the lungs to the peripheral tissues, and think of CO as the guy who takes oxygen's seat so that he can't ride the bus. CO is also the chemical that kills people in house fires from smoke inhalation.
Which chemical in tobacco smoke binds to hemoglobin causing red blood cells to carry less then their normal load of oxygen?
CO (carbon monoxide). It binds to the same sites on hemoglobin that oxygen would, except with a much greater affinity than oxygen does. Think of hemoglobin as a bus transporting oxygen from the lungs to the peripheral tissues, and think of CO as the guy who takes oxygen's seat so that he can't ride the bus. CO is also the chemical that kills people in house fires from smoke inhalation.
How many time greater is the affinity of hemoglobin for carbon monoxide greater than the affinity of hemoglobin for oxygen?
The affinity of hemoglobin for CO is roughly 20,000 times greater than that of oxygen in vitro. In vivo, the affinity of hemoglobin for CO is roughly 200-225 greater than that of oxygen. ------------------------------------------------------------------------------------------------- O2 has stronger bond than CO. Therefore, the oxygen in CO loves the iron in the hemoglobin as iron ends with two electrons which complete the 6 electrons in the oxygen. In vivo, the affinity of hemglobin for CO is about 153 from 141x153/141. by amin elsersawi
How does carbon monoxide impair the delivery of oxygen to tissue?
CO binds hemoglobin with a higher affinity than Oxygen. so hemoglobin bound to CO in the pulmonary capillaries will not become oxygenated. CO poisoning leads to hypoxia.
What can bond to hemoglobin and therefore deprive the body of oxygen?
CO
What is more dangerous CO or CO2?
Carbon monoxide binds very strongly to the iron atoms in hemoglobin, the principal oxygen-carrying compound in blood. The affinity between CO and hemoglobin is 200 times stronger than the affinity between hemoglobin and oxygen. When CO binds to the hemoglobin it cannot be released nearly as readily as oxygen would be. The preferential binding of carbon monoxide to heme iron is the main reason for carbon
What occurs when carbon monoxide enters the lungs?
When air is inspired, it goes into the lungs, spreads across the alveoli which are like air sacs, and increases the oxygen content in the blood (through capillaries) with the help of hemoglobin. At the same time, carbon dioxide is being transferred into the alveoli by the capillaries used to transfer blood. The oxygen rich blood is sent through the pulmonary vein into the right side of the heart where it is transferred to the rest of the body. Meanwhile, the carbon dioxide that had been collected by the air sacs in the lungs is expired.
What kind of bond are formed by share electrons?
When electrons are shared, covalent bonds are formed. Covalent bonds are of two types, polar and non-polar. A complex type of covalent bonds are co-ordinate covalent bonds or dative bonds.
