Zoology - Breathing and Exchange of Gases Question with Solution | TestHub

The various partial pressures in the respiratory system are tabulated as follows:



$\mathrm{p}{\mathrm{O}}_2$in atmospheric air is 159 mm Hg while$\mathrm{p}{\mathrm{O}}_2$in alveoli is 104 mm Hg.$\mathrm{p}{\mathrm{C}\mathrm{O}}_2$in oxygenated blood is 40 mm$\mathrm{H}\mathrm{g}$while$\mathrm{p}{\mathrm{O}}_2$in deoxygenated blood is 40 mm Hg.$\mathrm{p}{\mathrm{C}\mathrm{O}}_2$in oxygenated blood is 40 mm$\mathrm{H}\mathrm{g}$while${\mathrm{p}\mathrm{C}\mathrm{O}}_2$in tissues 45 mm Hg.$\mathrm{p}{\mathrm{O}}_2$in alveoli is 104 mm$\mathrm{H}\mathrm{g}$and$\mathrm{p}{\mathrm{O}}_2$in oxygenated blood is 95 mm Hg. These values are not equal
