WebbThe partial pressure of any gas can be calculated by: P = (Patm)— (percent content in mixture). P atm, the atmospheric pressure, is the sum of all of the partial pressures of the atmospheric gases added together, Patm = PN2 +PO2+ PH2O+ PCO2= 760 mm Hg. The pressure of the atmosphere at sea level is 760 mm Hg.
WebbGill lamellae are considered the definitive site of gas exchange, but some exchange also occurs across the filaments and arches. The gills are also functionally complex.

WebbThe humidified air enters the alveoli, where gas exchange occurs. In alveolar air, the values for PO2 and PCO2 are changed substantially when compared with inspired air. PAO2 is 100 mm Hg, which is less than the PO2 in inspired air, which is 160mm Hg, and PACO2 is 40 mm Hg, which is greater than the PCO2 in inspired air, which is close to 0mm Hg.
