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.
Smokers have lower concentrations of oxygen in their blood because smoking can damage the lungs and reduce their ability to take in oxygen from the air. This can lead to a decrease in the amount of oxygen that gets into the bloodstream, resulting in lower oxygen levels overall.
Smoking decreases the amount of oxygen that can be carried in the blood by replacing oxygen with carbon monoxide. This makes it harder for oxygen to bind with hemoglobin in red blood cells, leading to lower oxygen levels in the blood of smokers compared to non-smokers.
Oxygen diffuses from an alveolus to the blood around it because of the concentration gradient between the high oxygen concentration in the alveolus and the lower oxygen concentration in the blood. This process allows oxygen to move from the lungs into the bloodstream for transport to the body's cells.
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.
Oxygen diffuses from air into blood through the process of simple diffusion. This occurs in the lungs where oxygen moves from areas of high concentration in the alveoli to areas of lower concentration in the blood capillaries. The concentration gradient allows oxygen to pass through the alveolar walls and enter the blood.
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.
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.
Oxygen diffuses rapidly into the blood due to the concentration gradient between the alveoli in the lungs and the blood in the capillaries surrounding them. The alveoli have a high concentration of oxygen, while the blood has a lower concentration, which drives the diffusion of oxygen across the thin walls of the alveoli and capillaries. Additionally, the large surface area and short diffusion distance in the lungs help facilitate the rapid diffusion of oxygen into the blood.
Oxygen diffuses from red blood cells in the bloodstream into body tissues through capillaries. It moves from areas of higher concentration in the blood to areas of lower concentration in the tissues, where it is used for cellular respiration.
Oxygen diffuses into cells from the bloodstream due to a concentration gradient, where oxygen is higher in the blood compared to inside the cells. This diffusion occurs passively, moving from an area of higher concentration (blood) to an area of lower concentration (cells), to meet the cell's energy demands for cellular respiration.
The direction of diffusion for carbon dioxide and oxygen in the lungs and tissues is determined by their respective concentration gradients. In the lungs, carbon dioxide diffuses out of the blood into the alveoli where its concentration is lower, while oxygen diffuses into the blood from the alveoli where its concentration is higher. In the tissues, oxygen diffuses from the blood into the cells where its concentration is lower, and carbon dioxide diffuses from the cells into the blood where its concentration is higher.
alveoli in the lungs, where it passes through the thin walls of the capillaries surrounding the alveoli to enter the bloodstream. This process is driven by a concentration gradient, with oxygen moving from an area of high concentration in the alveoli to an area of lower concentration in the blood.
