Answer 9

volume

Question 10

the volume of air exchanged during a given task (can change)

Answer 10

tidal volume (TV)

Question 11

the volume of air that can be inspired with maximal effort after the inspiration phase of tidal breathing (keep inhalaing after normal inhalation)

Answer 11

inspiratory reserve volume (IRV)
