Bear in mind that this is a fairly comprehensive synthesis of multiple objectives in the chapter (see study guide B3, El, E2, E3, Fl, F3)
If your last name begins with the letter A - H:
1) Trace the path of a molecule of CO2 (and only CO2, not 02) as it moves from a metabolically active tissue into the blood and to the pulmonary capillaries.
2) Explain how the CO2 moves out of the pulmonary capillary and into an alveolus.
3) Trace the path of the molecule of CO2 as it leaves the alveolus and is released to the external environment.
Include the processes of internal respiration, external respiration, and ventilation facilitate the removal of CO2 from the body. Write your answer as 3 paragraphs.
