Document Summary
Body is 70% water, we can handle water but can"t tolerate increase in h+ maintain ph at about. 7. 34 bring in o2 to mop up h+ used in energy process. Size of breath that you take in 500 ml is the volume of air you breathe in you breathe out the same amount use some of the oxygen and replace it with some of the co2 coming off the. V=l/min usually measure expired air but can measure inspired air ve is frequency * tidal volume about 10 l /min (resting volume) Blow into a machine blow air into it and the bell inside will go up and pen will move against the paper we see this change that occurs from rest to maximal expiration. Alveolar volume volume of air that does take part in gas exchange permits oxygen getting into the blood stream and pick up co2 coming off the kreb"s cycle.
