Why are oxygen are the oxygen level's in a smoker's blood less than those in a non-smoker?

one major reason is that cigarette smoke contains tar which coats the avioli in the lungs. these are special projections in the lung that increase surface area (an increased surface area is proportional to an increased absorption rate, in this case dissolving oxygen gas on the moist membrane of the lung.) as the tar coats the avioli the available surface area decreases and therefore the absorption rate decreases. so essentially a smoker is getting less from each breath as a nonsmoker, this results in a lower blood-oxygen reading for a smoker. this also accounts for why smokers run out of breath sooner and a why they sometimes cough up black flem.

Could having one lunge cause low oxygen in blood?
Yes, but if you are searching for the reason a person has low oxygen levels this is most likely NOT the answer.
What is the medical term meaning condition of deficient oxygen in tissues?
The condition of deficient oxygen is hypoxia, and the condition of no oxygen is anoxia. Blood cells are aerobic so they need oxygen to survive. If you have below normal oxygen levels, you're not providing your blood with its fuel; you're basically starving your blood cells. Blood delivers oxygen to your tissues before returning to your lungs to fill up again. So if your blood isn't getting enough oxygen, neither will any other part of your body.
From where does the blood get oxygen?
The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
Where does blood get oxygen from?
Capillaries in your lungs provide oxygen to the haemoglobin molecules of red blood cells.
Does blood produce oxygen?
Yes - oxygen is held in red blood cells (in haemoglobin to be precise). As the blood flows, oxygen is brought all around the body and eventually gets back to the heart and lungs as carbon dioxide (which is what you exhale).
How does smoking affect carbon dioxide levels?
Smoking increases carbon monoxide levels in the blood as opposed to carbon dioxide. Carbon monoxide ties up hemoglobin so that smokers have lower blood oxygen levels. Chronic inflammation has been linked to the high levels of carbon dioxide that smokers breathe in as it is 200 times the atmospheric rate.
Why do smokers have lower concentration of oxygen in their blood than non smokers?
smoking cigarettes,cigars containing nicotine becomes addiction but there is a high intake of Co2 with the every puff that causes the haemoglobin to attach with Co2 replacing the oxygen in the blood cells.
A decrease in the blood's ability to transport oxygen is called what?
The correct name for low levels of oxygen in the blood is hypoxaemia. Low levels of oxygen in the body tissues is called hypoxia
What is saturated percentage of oxygen?
Saturated percentage of oxygen (SpO2) is a measurement of oxygen levels in the blood
What constant monitors levels of oxygen and carbon dioxide in the blood?
blood vessels
Why does a patient's oxygen levels fall as a result of red blood cells?
If the patient blood levels fall (maybe due to hemorrhage), the oxygen that the RBCs are carrying is lost with the blood. The person will feel 'out of breath'.
Is blood oxygen level monitored at medulla oblongata?
Yes it does monitor blood oxygen levels and it is located in the brain stem.
Levels of oxygen and carbon dioxide in the blood are tested by?
Oximetry.
How does the human body regulate blood oxygen levels?
chemoreceptors
How does human body regulate blood oxygen levels?

Which organ's blood flow pattern results in low oxygen levels causing vasoconstriction and high oxygen levels causing vasodilation?
lungs
What is anoxemia?
Loss or reduction of normal oxygen levels in the blood.
