Web9 dec. 2024 · Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled. WebThe oxygen transport from lungs to tissues is achieved because hemoglobin has the highest affinity for oxygen at 100 mm Hg PO2 (which is almost present in the alveolar air) and low affinity for oxygen at 40 mm Hg PO 2 which is prevalent in the tissues. Web13 mrt. 2024 · As the hemoglobin releases oxygen to the cells of the body, it binds with carbon dioxide molecules. The carbon dioxide is then carried back to the lungs to be exhaled.
