The partial pressure of oxygen in a pulmonary capillary is about 40 mm Hg. Determine the partial pressure that will promote movement of oxygen ^intothe pulmonary capillary from air in the alveolus. A) 35 mm Hg B) 40 mm Hg C) 104 mm Hg D) 18 mm Hg

Question

Quizplus · Accepted Answer

Oxygen will move from an area of higher partial pressure to an area of lower partial pressure. Therefore, a partial pressure of 104 mm Hg in the alveolus will promote the movement of oxygen into the pulmonary capillary, where the partial pressure is 40 mm Hg.

The Partial Pressure of Oxygen in a Pulmonary Capillary Is
