BIOC33H3 Lecture Notes - Globulin, Hydration Reaction, Carbonic Anhydrase
Document Summary
Midterm: anything not covered on exam will not be on exam - anything after this lec, 50-60 mcq, calculations will be simple - no calculators allowed. Partial pressure of gases: partial pressure of a gas: the pressure exerted by a given gas within a gas mixture, partial pressure of o2 = ~160 mmhg, pco2 = 0. 23 mmhg ~ 0 mmhg. Go from 160mmhg in atm to 100mmhg in alveoli because some o2 has gone to blood. Perfusion limitation - see in humans and most mammals. Diffusion limitation - seen in gill-breathing fish: graphs. Perfusion limitation dependent on blood flow sent to the lungs cardiac output. = amount of o2 that can be delivered to tissues is: left = po2 (right = pco2) Mixed venous po2 blood enters lungs with 40 mmhg and leaves with a partial pressure of 100 mmhg.
