respiratory system

Question 1

ventilation

Answer 1

(breathing)
the overall exchange of gases btw the atmosphere, blood, and cells

Question 2

external respiration

Answer 2

(pulmonary) the exchange of respiratory gases btw lungs and blood

Question 3

Internal respiration

Answer 3

(tissue) the exchange of respiratory gases btw blood and body cells

Question 4

cellular respiration

Answer 4

occurs in mitochondria and is oxidation of glucose to produce ATP

Question 5

when you burn things you get?

Answer 5

carbon monoxide

Question 6

larynx is your?

Answer 6

voice box

Question 7

laryngitis

Answer 7

an inflammation of your voice box (larynx) from overuse, irritation or infection

Question 8

alveoli

Answer 8

functional unit of the lung

Question 9

respiratory system consists of the

Answer 9

nose
pharynx (throat)
larynx (voice box)
trachea (windpipe)
bronchi
lungs

Question 10

upper respiratory system

Answer 10

nose
nasal cavity
pharynx
and associated structures

Question 11

lower respiratory system

Answer 11

larynx
trachea
bronchi
lungs

Question 12

inhalation (inspiration)

Answer 12

breathing in
air pressure inside the lungs is equal to air pressure of the atmosphere

Question 13

exhalation (expiration)

Answer 13

breathing out
pressure in lungs is greater than pressure of atmosphere

Question 14

alveoli is surrounded with ________ to exchange oxygen with _________

Answer 14

capillaries
CO2

Question 15

Alveoli has

Answer 15

air space with moisture but NOT wet

Question 16

Macrophages are not suppose to be in ?

Answer 16

alveoli

Question 17

surfactants

Answer 17

hold alveoli open to receive air
mixture of lipoproteins and phospholipids present in alveolar fluid reduces its surface tension below the surface tension of pure water
prevents alveoli from collapsing

Question 18

pneumonia

Answer 18

fluid in alveoli making it hard to breath and can collapse alveoli when fluid comes out

Question 19

external costal and diaphragm

Answer 19

expands size of thoracic cavity causing inhalation

Question 20

internal costal and diaphragm

Answer 20

reduces size of thoracic cavity causing expiration

Question 21

how many times do we breath per minute?

Answer 21

x14

Question 22

Tidal volume

Answer 22

normal resting breathing

Question 23

spirometer

Answer 23

measures volumes and capacities
looks to see your vital capacity

Question 24

vital capacity

Answer 24

sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume

Question 25

tidal volume

Answer 25

volume of one breath

Question 26

total lung capacity

Answer 26

sum of vital capacity and residual volume

Question 27

inspiratory reserve volume

Answer 27

the additional inhaled air after taking a deep breath of more than 500ml

Question 28

expiatory reserve volume

Answer 28

the extra air pushed out after exhaling as forcibly as possible

Question 29

atmosphere air is approximately

Answer 29

80% nitrogen gas
15% oxygen

Question 30

examples of upper respiratory tract infection

Answer 30

common cold –> rhinovirus
influenza –> flu
sinusitis –>usually bacterial

Question 31

bronchitis

Answer 31

condition that develops when the airways in the lungs, called bronchial tubes, become inflamed and cause coughing, often with mucus productio

Question 32

asthma

Answer 32

inflammation in bronchi and bronchioles causing swelling and reduction in lumen where air goes through

Question 33

pulmonary fibrosis

Answer 33

scar tissue in lungs create less flexibility
can be caused by many particle types such as dust, ceramic, and sandblasting particles

Question 34

emphysema

Answer 34

lose flexibility in alveoli as it can expand but cannot retract. Causing you to not be able to get rid of CO2
will give patients pure O2

Question 35

tuberculosis

Answer 35

lower respiratory tract disease
bacterial airborne

Question 36

lung volume
