3) Which of the following is not true about the structure of an alveolus?

:It has thick walls to trap gases that enter during breathing.***
:It has many capillaries running through it's structure.
:It has high surface area to allow lots of gas exchange.
:It has a high concentration of oxygen and a low concentration of carbon dioxide.

4) Pneumonia is a disease that causes fluid to build up in the alveoli of the lungs. Which of the following would you expect to be impaired in patients with pneumonia?

:Movement of carbon dioxide out of body cells.

5) Which of the following would be true during the inhalation phase of breathing?

:The lungs are inflated, oxygen concentration is high, and carbon dioxide concentration is low in the alveoli.***
:The lungs are deflated, oxygen concentration is high, and carbon dioxide concentration is low in the alveoli.
:The lungs are inflated, oxygen concentration is low, and carbon dioxide concentration is high in the alveoli.
:The lungs are deflated, oxygen concentration is low, and carbon dioxide concentration is high in the alveoli.
