Gas exchange in the lungs, blood and tissues Osmosis

WebInternal respiration is gas exchange that occurs at the level of body tissues ( Figure 22.4.3 ). Similar to external respiration, internal respiration also occurs as simple diffusion due to a partial pressure gradient. However, the partial pressure gradients are opposite of those present at the respiratory membrane. Web2 mrt. 2024 · Since blood PO2 measurements are not directly affected by the oxygen in red blood cells, the PO2 does not provide a measurement of the total oxygen content of whole blood. It does, however, provide a good index of lung function. If the inspired air had a normal PO2 but the arterial PO2 was below normal, for example, you could conclude that …
