1600 Exam 4 - Respiratory and Acid/Base
1. gas exchange: The primary function of the lungs is .
2. ventilation: getting air to the tissues is called
3. perfusion: getting blood to the tissues is called
4. diffusion: the movement of O2 and CO2 in the body is called
5. nasopharynx, oropharynx, and laryngopharynx: The 3 parts of the upper airway are:
6. larynx, trachea, bronchi, bronchipulmonary segments, and bronchioles: The 5
parts of the lower airway are:
7. cilia: line the trachea and bronchi; defense against invaders
8. 300 million: There are approximately alveoli
9. alveoli: grapelike clusters of air filled sacs
10. gas exchange: type 1 alveoli cells are for:
1/8
,11. surfactant: type 2 alveoli cells are for:
12. surfactant: a chemical substance that keeps the alveoli from collapsing
13. 3: The right lung has lobes.
14. 2: The left lung has lobes
15. bronchial artery: The system supplies oxygenated blood to lungs and pleura
16. pulmonary artery: The system is a vast network of capillaries that allows for gas exchange
17. proprioceptors: are sensitive to exercise
18. chemoreceptors: respond to changes in pH and pCO2
19. baroreceptors: respond to changes in BP
20. gravity: Blood flow to alveoli is affected by .
21. fluid volume in lungs, fluid shifts, interstitial edema, and alveolar edema: 4
2/8
, Factors affecting perfusion
22. 25: % of pulmonary capillaries are perfused at rest
23. 22/8 to 25/8 mm Hg: Normal pressure in the pulmonary capillary network is: to
24. minimal: Pulmonary blood flow in zone 1 has perfusion
25. intermittent: Pulmonary blood flow in zone 2 has perfusion
26. continual: Pulmonary blood flow in zone 3 has perfusion
27. 4: Normal ventilation (VA) is L/min
28. 5: Normal perfusion (Q) is L/min
29. 0.8: Normal VA/Q ratio is
30. high V/Q, low V/Q, or shunt: Ventilation/Perfusion imbalance may be because of: (3)
3/8
