Respiratory System

Question 1

trachea

Answer 1

windpipe, rigid cartilage tube lined with hairs that filter air, divides into two pipes

Question 2

bronchi

Answer 2

two pipes of trachea, L and R bronchus

Question 3

valsalva effect

Answer 3

incorrect breathing during exercise, forcefully trying to exhale air against closed airway

Question 4

inhale (diaphragm)

Answer 4

contracts, increases volume of chest cavity

Question 5

alveoli

Answer 5

air sacs surrounded by pulmonary capilleries

• located in clusters at end of bronchioles
• gaseous exchange takes place

Question 6

exhale (diaphragm)

Answer 6

relaxes, volume of chest cavity decreases

Question 7

diaphragm

Answer 7

separates chest cavity from abs

Question 8

which lung is bigger

Answer 8

right lung (3 lobes)

Question 9

ethmoid sinus

Answer 9

filter air that goes inside nasal cavity

Question 10

eustachian tubes

Answer 10

connect pharynx with middle ears

Question 11

voice box

Answer 11

larynx

Question 12

air mix

Answer 12

21% o2, .04% co2, 79% nitrogen

Question 13

trachea connect

Answer 13

larynx to bronchi

Question 14

lungs

Answer 14

intake o2, remove co2

Question 15

capillaries covering alveoli

Answer 15

allow o2 to diffuse into blood anc co2 in lungs to be exhaled

Question 16

main muscles in breathing

Answer 16

diaphragm and intercostals

Question 17

gaseous exchange in lungs

Answer 17

o2 diffuses into bloodstream from respiratory tract

Question 18

breathing pathway

Answer 18

pharynx>larynx>epiglottis>trachea>bronchi>bronchioles>alvioli

Question 19

diffusion

Answer 19

molecules pass from an area of greatet concentration (high pressure) to an area of lesser concentration (lower pressure)

Question 20

gaseous exchange

Answer 20

diffusion- o2 through alveoli to capillary walls into bloodstream
co2 travels from blood to alveoli

Question 21

bronchioles

Answer 21

branch out further leading to alveoli

Question 22

bronchus

Answer 22

enters lung and divides into bronchioles
