Which of the following correctly describes the events at the alveoli?Blood leaves the alveoli with a partial pressure of 45mmHg carbon dioxideBlood enters the alveoli with a partial pressure of 40mmHg carbon dioxideBlood leaves the alveoli with a partial pressure of 100mmHg oxygenBlood enters the alveoli with a partial pressure of 30mmHg oxygen

In the alveoli with low ventilation to perfusion ratio:Question 8Select one:a.The blood leaving the alveoli has lower CO2 than the blood entering the alveoli.b.The blood leaving the alveoli has the same CO2 as the blood entering the alveoli.c.The blood leaving the alveoli has higher O2 than the blood entering the alveoli.d.The blood leaving the alveoli has higher CO2 than the blood entering the alveoli.
