Answer 9

decreases

Question 10

during speech, lung volume:

Answer 10

decreases

Question 11

the alveolar pressure is – at EEL

Answer 11

0

Question 12

we inhale to a ——- lung volume before speaking loudly to generate ——— recoil pressures

Answer 12

higher, larger

Question 13

contraction of the internal intercostal muscles causes an ———– in alveolar pressure

Answer 13

increase

Question 14

contraction of the diaphragm causes a ———- in alveolar pressure

Answer 14

decrease

Question 15

apnea

Answer 15

the cessation of breathing at the end of a tidal volume expiration

Question 16

eupnea

Answer 16

normal, quiet breathing

Question 17

hypernea

Answer 17

increased depth (and sometimes frequency) of breathing at rest

Question 18

effects of pulmonary fibrosis on respiration

Answer 18

rest breathing is shallower than normal

increases elastic recoil

Question 19

if recoil force is GREATER than required subglottal pressure demand, what will the speaker do?

Answer 19

use checking action to reduce recoil pressure

Question 20

if recoil force is LESS than the required subglottal pressure demand, what will the speaker do?

Answer 20

use expiratory muscle force to add to recoil pressure

Question 21

muscles of checking action

Answer 21

external intercostals

Question 22

characteristics of someone with a spinal cord cut at the level of C7

Answer 22

Would have difficulty with speech due to inability to generate expiratory muscle force

Would have some difficulty with speech due to problems providing checking action

Question 23

characteristics of somoene with spinal cord cut at level of C2

Answer 23

unable to inspire on their own

Would have difficulty with speech due to inability to generate expiratory muscle force

Would have some difficulty with speech due to problems providing checking action

Question 24

reference pressure for measurement of respiratory pressure

Answer 24

atmospheric pressure

Question 25

intraoral pressure

Answer 25

pressure that is measured in the mouth

Question 26
