Week 6

Question 1

1st order of subsystem management

Answer 1

respiration (resonance)

Question 2

2nd order of subsystem management

Answer 2

phonation (rate)

Question 3

3rd order of subsystem management

Answer 3

articulation (prosody)

Question 4

what are the two muscles involved in inspiration

Answer 4

diaphragm and internal intercostal muscles

Question 5

inspiration

Answer 5

breathing in
-chest expands
-diaphragm flattens and contracts

Question 6

exhalation

Answer 6

breathing out
-passive process (exhalation)
-chest contracts
-diaphragm relaxes

Question 7

tidal volume (TV)

Answer 7

volume of air for one cycle of quiet breathing
-M 600 ml and F 450 ml

Question 8

inspiratory reserve volume (IRV)

Answer 8

volume that can be inhaled after tidal inspiration- 2500ml

Question 9

expiratory reserve volume (ERV)

Answer 9

volume that can be exhaled after tidal expiration (resting lung volume, 1000ml

Question 10

residual volume (RV)

Answer 10

volume of air remaining after maximum expiration, 1100 ml
-inside alveoli

Question 11

dead air space

Answer 11

anatomical and physiological 150 ml (amount that remains in lungs after maximal exhalation)
-maintained in respiratory tract so doesn’t participate in any gas exchange and cannot reach vascularized alveoli

Question 12

inspiratory reserve volume plus tidal volume equals

Answer 12

inspiratory capacity

Question 13

IRV + TV + ERV

Answer 13

vital capacity

Question 14

FRC (functional residual capacity) + inspiratory capacity

Answer 14

total lung capacity
