decrease

Question 7

can residual volume be measured?

Answer 7

no

Question 8

what is the tidal volume?

Answer 8

volume of air moved in or out of the lungs in a quiet breath (in OR out)

Question 9

what is the normal range for ERV?

Answer 9

about 1000mL in males and 700mL in females

Question 10

Answer 10

hyaline cartilage of trachea

Question 11

after hyperventilating in fresh air, blood carbon dioxide increases or decreases?

Answer 11

decreases

Question 12

Answer 12

diaphram (striations)

Question 13

Answer 13

Alveoli

Question 15

what equipment do you nee for the human respiratory volume test?

Answer 15

1) nose clip 2) mouthpiece 3) filter 4) spirometry pad 5) flow head

Question 16

what is residual volume (RV)?

Answer 16

amount of air left in lungs after forceful exhalation

Question 17

what is the normal range for RV?

Answer 17

1200mL in males and 1100mL in females

Question 18

what is the inspiratory reserve volume (IRV)?

Answer 18

normal inhale followed by forceful inhale

Question 19

what is the normal range for tidal volume (TV)

Answer 19

400-500mL

Question 20

what is the trachea lined with?

Answer 20

pseudostratified columnar epithelium

Question 21

what is vital capacity (VC)?

Answer 21

forceful inhale followed by forceful exhale

Question 22

what is the normal range for IRV?

Answer 22

3000 mL in males and 1900 mL in females

Question 23

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

Answer 23

increase

Question 24

what is the formula for IRV?

Answer 24

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

Question 25

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

Answer 25

directly

Question 26

what is Expiratory Reserve Volume (ERV)?

Answer 26

normal exhale followed by forceful exhale

Question 27

what does hyperventilation decrease and why?

Answer 27

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