In the lung's alveoli, there are four gases mixed together: oxygen, carbon dioxide, nitrogen, and water vapor. At a normal barometric pressure of 760 mm Hg, alveolar O2 exerts a partial pressure of 100 mm Hg, CO2 40 mm Hg, and water vapor 47 mm Hg. What is the alveolar partial pressure of nitrogen? → 573 mm Hg
Which of the following equations can be used to calculate the pressure exerted by a liquid? → liquid pressure = liquid density ´ liquid depth
