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.

Why smokers have a lower concentration of oxygen in their blood than non smokers?
Smoking is a leading cause of premature death. Red blood cell (RBC) membrane lipids are rich in polyunsaturated fatty acids; therefore, the effect of oxygen on RBC membranes is more prominent than on other body tissues. The attachment of peroxidants to RBC membranes can result in hemolysis.
How does your blood turn from Oxygenated to deoxygenated?
Your blood is never truly dexoygenated, but as it delivers oxygen to tissues the saturation of oxygen gets lower. When the blood reaches the alveoli of the lung oxygen diffuse from the higher concentration of the air to the lower concentration of the blood, where most of it binds to hemoglobin molecules.
Which is used for oxygen transportation in living organisms?
Im guessing you were asking whether diffusion, osmosis or active transport is used for oxygen transportation in organisms. Diffusion is the random movement of particles from an area with a high concentration to an area with a lower concentration. So in humans for eample, gas exchange occurs in the lungs where there is a lower concentration of oxygen in the blood and a high conc of oxygen in the lungs. The oxygen then diffuses into the blood.
How does oxygen move from the capillaries to cells?
Through diffusion. There is less oxygen in the cells as opposed to the capillaries, so through simple diffusion, the oxygen goes from an area of high concentration to lower concentration.
Why our body cells have a different oxygen concentration compared to the blood flowing to them from our lungs?
Diffusion from high concentration to low concentration.The oxygen concentration in the air in the lungs is higher than in the blood.The oxygen concentration in the blood is higher than in body cells.If these differences in concentration did not exist oxygen could not move from the air to the blood to body cells. While we are alive body cells consume some of the oxygen they receive, reducing their oxygen concentration and maintaining these differences. When we die the body cells quit consuming oxygen and over a period of time the levels of oxygen slowly begin evening out (however as blood no longer moves from the lungs to the body oxygen diffusion slows dramatically, leaving some body cells with much lower oxygen levels than would be normal).
Why you inhale oxygen only?
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore there will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium
How is blood oxygenated in the lungs?
The operating principle is a process called diffusion, which causes a substance to move from a region of high concentration to a region of lower concentration. Think of a squirt of perfume diffusing from a corner in a room until you can smell it everywhere in the room. Blood returning from the body to the lungs has a higher percentage of carbon dioxide (CO2) than the air inhaled into the lungs does. Conversely the concentration of oxygen (O2) in the inhaled air is greater than the concentration of O2 in the returning blood. Haemoglobin, which can (loosely) bond to both O2 and CO2, facilitates the exchange of gasses from respective regions of high concentration to the regions of lower concentration. Specifically, CO2 moves from the returning blood (higher concentration) to the air in the lungs (lower concentration) and oxygen moves in the other direction, thus oxygenating the blood.
What is the maximum o2 that can be carried in arterial blood?
The maximum amount of oxygen that can be carried in arterial blood is approximately 20.2 mmol/L. This is equivalent to about 98.5% of the oxygen that is dissolved in the plasma. The remaining 1.5% is bound to hemoglobin and is termed oxyhemoglobin. The amount of oxygen that can be carried by the blood is dependent on the concentration of hemoglobin in the blood as well as the oxygen saturation of hemoglobin. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment which is why the amount of oxygen that can be carried varies in different environments. The following factors affect the amount of oxygen that can be carried in arterial blood: Hemoglobin concentration Oxygen saturation of hemoglobin Partial pressure of oxygen in the environmentHemoglobin is a protein in red blood cells that binds to oxygen and carries it throughout the body. The concentration of hemoglobin in the blood is an important factor in determining how much oxygen can be carried. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment. This means that the amount of oxygen that can be carried in the blood varies in different environments. For example in a high-altitude environment where the partial pressure of oxygen is lower the oxygen saturation of hemoglobin is also lower resulting in less oxygen being carried in the blood.

How your lungs refine oxygen from other gases?
Your lungs refine oxygen from the other gases in air because the gases diffuse through the cell walls in the alveoli in your lungs through osmosis (higher concentration of gases in the air than in the blood, so gases move from the higher concentration to the lower concentration) where they contact the red blood cells. The hemoglobin in the red blood cells binds to the oxygen and leaves all the other gases alone. It moves on from the lungs and delivers the oxygen to the rest of the body. It's the hemoglobin that does the work.
How does oxygen move into the bloodstreem?
The oxygen diffuses through the thin lining of the alveoli into the blood. It moves from the area of high oxygen concentration (the alveoli) to the area of low oxygen concentration (the blood).
What binds hemoglobin instead of oxygen in smokers?
Nothing binds to hemoglobin instead of oxygen in the lungs in smokers. In the lungs oxygen is bound to hemoglobing for transport to organs and tissues while carbon-dioxide is release in the lungs for expiration. You are probably thinking about the fact that smokers have lower oxygen uptake during inspiration than non-smokers. 1. Cigarettes fill your lungs with tare and makes them function at a lower quality than healthy lungs. It lowers the ammount of air you are able to inhale thus decreasing the ammount of oxygen. 2. Nicotine is a vasoconstrictor thus blood flow is impaired to your whole body. In the opposite reaction when you work out and need more energy to e.g. specific muscles, the body dilates those vessels leading there to get more oxygen to that area.
