Anatomy Final Exam

Question Answer
1. Maximum air movement in the lungs vital capacity
2. Which of the following is the most abundant gas in the air? Nitrogen
3. The lining of the trachea is: ciliated columnar epithelium
4. Airways that supply one lobe of a lung are called: Secondary Bronchi
5. The elastic structure that folds back over the glottis, preventing the entry of liquids or solid food into the respiratory tract during swallowing, is the epiglottis.
6. The layer of serous membrane that covers the surface of the lungs is the: visceral pleura
7. Surfactant: plays a key role in keeping alveoli open
8. Most of the carbon dioxide transported by the blood(approximately 70%) is: ultimately transported as bicarbonate ions in the plasma
9. Levels of which of the following are responsible for regulating respiratory activities under normal conditions? carbon dioxide
10. When at rest, the amount of air that enters and leaves the lungs in a normal respiratory cycle is the: tidal volume.
11. The actual sites of gas exchange within the lungs are: Alveolar
12. Right Lung has how many lobs: 3
13. Left Lung has how many lobs: 2
14. Lob tissue is: ciliated columnar epithelium
15. Alveolar tissue is: simple squamous epithelium
16. thyroid cartilage is: the lining of the Adams apple
17. Partial pressure gradient for CO2 in the lungs is less steep: Venous blood Pco2 = 45 mm Hg Alveolar Pco2 = 40 mm Hg
18. Partial pressure gradient for O2 in the lungs is steep: Venous blood Po2 = 40 mm Hg
19. Alveolar Po2: 100 mm Hg
20. Molecular O2 is carried in the blood: 1% dissolved in plasma: 99% loosely bound to each Fe of hemoglobin (Hb) in RBCs
21. CO2 is transported in the blood in three forms 1.) 7 to 10% dissolved in plasma. 2.) 20% bound to globin of hemoglobin (carbaminohemoglobin). 3.) 70% transported as bicarbonate ions (HCO3-) in plasma.
22. Make more 02 when: exercising
23. Hold breath: PCo2 with go up to increase breathing
