1) Why would the anterior portion of the nose be cartilageinstead of bone?

2) Some elderly patients have difficulty swallowing and closingtheir epiglottis. Would this cause any potential problems in therespiratory system?

3) What are the two things shown or implied in slide 26 thatwork together for a particular goal? What is their purpose? Ifeither is not performing, would performance be compromised?

4) Slide 40 shows emphysema reducing the total surface area ofthe alveoli. Where else have we seen surface area being importantin A&P?

5) OPTIONAL Draw two close segments of the lung (schematically)and draw why infections going from one to another are somewhatinhibited because of the anatomy. Draw the same two area butwithout being contained in segments and draw why an infection cango more easily from one of the regions to the other region.

6) Referring to the oxygen-hemoglobin dissociation curve (slide76), would a healthy patient benefit from breathing in a higherpercentage of O2 such as when visiting an “oxygen bar”. Would therepotentially be any benefit via a different route than hemoglobin(but isn’t)?

7) Relate the three factors affecting the affinity of Hb for O2on slide 77, to exercise. Does each have any connection toexercise?

8) Since a person always needs oxygen, why would the bronchioleshave the ability to contract at all? Why would the trachea not havethat ability?
