Q

what is residual volume (RV)?

A

amount of air left in lungs after forceful exhalation

17
Q

what is the normal range for RV?

A

1200mL in males and 1100mL in females

18
Q

what is the inspiratory reserve volume (IRV)?

A

normal inhale followed by forceful inhale

19
Q

what is the normal range for tidal volume (TV)

A

400-500mL

20
Q

what is the trachea lined with?

A

pseudostratified columnar epithelium

21
Q

what is vital capacity (VC)?

A

forceful inhale followed by forceful exhale

22
Q

what is the normal range for IRV?

A

3000 mL in males and 1900 mL in females

23
Q

hyperventilation into the paper bag causes the blood carbon dioxide content to decrease or increase?

A

increase

24
Q

what is the formula for IRV?

A

VC= TV + ERV + IRV which rearranges to IRV=VC (TV + ERV)

25
Q

can you conclude that the rate and depth of respirations are inversely or directly related to carbon dioxide levels?

A

directly

26
Q

what is Expiratory Reserve Volume (ERV)?

A

normal exhale followed by forceful exhale

27
Q

what does hyperventilation decrease and why?

A

carbon dioxide so it takes longer for it to accumulate high enough to stimulate respiration
