How is carbon dioxide carried by the blood?

its carried by the blood through a darker substance. Combined with haemoglobin as carboxyhaemoglobin,as bicarbonates in plasma and By dissolving in blood plasma.


What blood part carries carbon dioxide back to the lungs to be exhaled?

The haemoglobine found in the red blood corpuscles carries the carbon dioxide in the form of carboxyhaemoglobin .


What is the function on haemoglobin?

It helps in transport of O2 and CO2 It gives the red colour to the blood Haemoglobin will combine also with carbon monoxide to form carboxyhaemoglobin, which has the effect of reducing the amount of oxygen that can be carried in the blood.


Why wold carboxyhaemoglobin lead to death?

Carboxyhemoglobin is formed when carbon monoxide binds to hemoglobin in red blood cells, preventing oxygen from being transported throughout the body. This leads to tissue hypoxia, where organs and tissues are deprived of oxygen necessary for cellular function. As vital organs fail due to lack of oxygen, it can result in unconsciousness, brain damage, and ultimately death if exposure continues and oxygen levels aren't restored.


What is carbon-monoxide poisining?

Carbon monoxide poisoning happens when CO is absorbed into the haemoglobin rather than oxygen. The carboxyhaemoglobin is more stable than the oxyhaemolobin and essentially takes the haemoglobin "out of service" as a medium for transferring oxygen to the cells.


How is carbon monoxide produced and how does it act as a poison?

Carbon monoxide is produced by incomplete combustion of hydrocarbons. Haemoglobin in your blood is not a stable compound, such that it can transport oxygen around your body. What carbon monoxide does is to react with the haemoglobin to form carboxyhaemoglobin, which is a stable compound, and you wouldn't get enough oxygen, which then you die of asphyxiation (if I didn't forget anything).

How long does carbon monoxide stay in your system once you've stopped smoking?

Source from Cirric on Yahoo Answers (who got it from "the web") : Hi. From the web: "Carbon monoxide, like oxygen, has an affinity for iron-containing molecules, but it is about 210 times more effective in binding to iron-containing haemoglobin than oxygen is. Since air contains 21% oxygen this means that only 0.1% carbon monoxide in the air will eventually lead to 50% of the haemoglobin being combined to form carboxyhaemoglobin. Once carboxyhaemoglobin is formed, and after exposure ceases, it takes 4-5 hours for its level in the blood to fall, exponentially, by 50%. The ill effect of the gas can therefore be cumulative, and a person can be poisoned by intermittent exposure during the day." Source in related links
