Lab practical 1

Question 1

tidal volume

Answer 1

normal volume of air displaced between normal inhalation and exhalation when no extra effort applied (quiet breathing)

Question 2

IRV

Answer 2

additional amount of air that can be inhaled after normal inspiration (difference between max inspiration and TV)

Question 3

ERV

Answer 3

the amount of air above normal breath, exhaled during a forceful breath out

Question 4

RV

Answer 4

the amount of air that remains in the lungs after fully exhaling (keep lungs open)

Question 5

vital capacity

Answer 5

greatest volume of air expelled from lungs after taking deepest breath possible

Question 6

inspiratory capacity

Answer 6

max volume of air that can be inspired after normal expiration

Question 7

functional residual capacity

Answer 7

volume of air left in lungs at the end of passive expiration

Question 8

total lung capacity

Answer 8

volume of air in the lungs at the end of max inspiration

Question 9

total lung capacity equation

Answer 9

TLC= IRV +TV + ERV= RV
