Gonzalo Posted October 17, 2011 Report Share Posted October 17, 2011 Heeelloo! I have a Biology test in exactly 5 hours covering the liver, circulatory system and the gas exchange. I've been studying for over a week now but I still cannot fully comprehend what the gas exchange is all about because I get really confused when explanations begin involving partial pressures. I just cant get my head around it. I am also confused by the "intricate" qualities of the explanations I've been reading online for H6.3: "Describe how CO2 is carried by the blood, including the action of carbonic anhydrase, the chloride shift and buffering by plasma proteins"..... Please help me and save my grade? Reply Link to post Share on other sites More sharing options...
