filters, warms, and humidifies air
makes speech and sound possible
helps with smell
oxygen in, co2 out

Question 2

3 parts of the respiratory tract

Answer 2

nose
pharnyx
larnyx

head cold

Question 3

3 parts of lower respiratory tract

Answer 3

trachea
bronchial tree
lungs

chest cold

Question 4

pathway of respiratory system

pharnyx
epiglottis
larnyx
trachea
bronchi
bronchial tubes
alveoli

Question 5

how does the nose filter air

Answer 5

from mucous and hair

Question 6

pharnyx

Answer 6

throat

Question 7

larnyx

Answer 7

voice box

Question 8

bronchi

Answer 8

branch off into lungs

Question 9

alveoli

Answer 9

capillaries surround to pick up oxygen

Question 10

2 layers of pleura

Answer 10

visceral

parietal

Question 11

visceral pleura

Answer 11

lungs

Question 12

parietal pleura

Answer 12

lines cavity

Question 13

job of pleura

Answer 13

smooth and slippery so lungs don’t stick to other things

Question 14

respiration

Answer 14

exchange of gas

Question 15

pulmonary ventilation

Answer 15

breathing

moves air in and out of lungs

Question 16

three types of respiration

Answer 16

external
internal
cellular

Question 17

external respiration

Answer 17

exchange of gases between air in LUNGS and BLOOD

Question 18

internal respiration

Answer 18

exchange of gases between BLOOD and CELLS

Question 19

cellular respiration

Answer 19

oxygen to cells to make ATP

Question 20

inspiration

Answer 20

moves air into lungs; lungs expand

diaphragm contracts and flattens to reduce air pressure

Question 21

expiration

Answer 21

air moves out of lungs

diaphragm relaxes and moves up; increase air pressure

Question 22

tidal volume

Answer 22

normal volume of air into and out of lungs (500 ml)

Question 23

vital capacity

Answer 23

largest amount of air that we breathe out in one expiration (4800 ml)

Question 24

expiratory reserve volume

Answer 24

amount of air that can be forcibly exhales after expiring tidal volume

Question 25

inspiratory reserve volume

Answer 25

amount of air that can be forcibly inspired over and above normal inspiration

Question 26

residual volume

Answer 26

air that remains in lungs after most forcible expiration

Question 27

Eupnea

Answer 27

Normal breathing

Question 28

Hyperventilation

Answer 28

Breathe too fast

Question 29

Hypoventilation

Answer 29

Breathe too slow

Question 30

Dyspnea

Answer 30

Labored/difficult breathing

Question 31

Apnea

Answer 31

Breathing stops for brief period

Respiratory arrest

Question 32

Where does the regulation of respiration take place

Answer 32

Control centers in medulla and pons

Question 33

What can voluntarily speed up and slow down breathing

Answer 33

Cerebral cortex

Question 34

How does the cerebral cortex influence respiration

Answer 34

Changes rate at which neurons fire

Question 35

What tells our body when we have too much CO2 in it

Answer 35

Chemoreceptors and pulmonary stretch receptors

Question 36

Respiratory mucosa

Answer 36

Lining of respiratory tree

Question 37

How does the respiratory mucosa work

Answer 37

Makes mucous to trap things and make smooth
125 ml per day
Cilia beat up during cough

Question 38

Respiratory membrane

Answer 38

In lungs where oxygen and co2 exchange happens (alveoli and capillaries)
