... and and perfusion for gas exchange to be efficient, but things get a bit foggy after that. "In alveoli where ventilation is inadequate, PO2 is inadequate. As a result the terminal arterioles constrict and blood is redirected to respiratory areas where PO2 is is high and oxygen pickup ...

... than in the afferent arteriole because it is the same amount of O2 in less plasma. This makes sense. However the textbook also says that the pO2 stays virtually the same in both arterioles. This I don't understand as the pO2 depends on the concentration of O2 in the substance and the concentrations ...

some of our cells do burst if the water potential is strange in the blood, for instance if the plasma has a pO2 of -20 and a red blood cell has -10 then the water will leave the cell and it will shrivel as it travels along the concentration gradient also if the pO2 was reversed ...

... pressure when these two areas are separated by a membrane which will allow the gas to pass through it. When there is a higher pressure of oxygen (PO2) in the capillary than there is in the tissue immediately around the capillary, oxygen goes out of the blood and into the tissue. Same thing in ...
