inner; 2

Question 2

prevents collapse of alveolus during expiration

Answer 2

surfactant

Question 3

Boyle’s Law

Answer 3

air moves from high to low pressure

Question 4

central chemoreceptors

Answer 4

located in the medulla; responds quickly to increase PCO2 in arterial blood and decreased pH in CSF

Question 5

peripheral chemoreceptors

Answer 5

located in carotid and aortic bodies; sensitive to changes in arterial blood

Question 6

hypercapnia

Answer 6

increased levels of PCO2; results in respiratory acidosis- increased ventilation to compensate

Question 7

hypocapnia

Answer 7

decreased PCO2; can be caused by hyperventilation (respiratory alkalosis)

Question 8

extrinsic asthma

Answer 8

acute episodes triggered by type 1 hypersensitivity reaction to allergens

Question 9

intrinsic asthma

Answer 9

hyper-responsive tissue in airway initiates attack (respiratory infection, cold stress, cigs)

Answer 10

emphysema

Answer 13

pulmonary edema

Question 14

atelectasis

Answer 14

lung collapse

Question 15

plural effusion

Answer 15

presence of excessive fluid in the pleural cavity

Question 16

decreased ERV and FEV

Answer 16

COPD

Question 17

decreased IRV

Answer 17

inspiratory restrictions (restrictive lung disease)

Question 18
