Respiratory

Question 1

list

Upper respiratory track

Answer 1

nose, pharynx, larynx

Question 2

… made of

nose

Answer 2

turbinates and sinuses

Question 3

what do … do, and list the sinuses

sinuses

Answer 3

mositen and warm air
lighten skull
ethmoid, sphenoid, frontal, and maxilary

Question 4

…made of

Pharynx

Answer 4

nasopharynx, oropharynx, & laryngopharynx

Question 5

list

unparied cartilage

Answer 5

thyroid cartilage, cricoid, epilottis

Question 6

list

paired cartilage

Answer 6

arytenoid, corniculate, cuneiform

Question 7

true or false and what do they do

vocal folds

Answer 7

true vocal cords - produce sound

Question 8

true or false and what do they do

vestibular folds

Answer 8

false, help cover the glottis

Question 9

what is it made of and what does it do

trachea

Answer 9

consists of carlaginist rings, and brings air into lungs

Question 10

carina of trachea

Answer 10

where the trachea bifricates (splits) into bronchi in the lungs

Question 11

where do they enter and what happens to them when they do

primary bronchi

Answer 11

go into hilum of the lungs and then bifricated into secondary bronchi

Question 12

how many in each lung? and what happens to them in the lungs

secondary bronchi

Answer 12

2 in the left lunch, 3 in the right lung, all bifircated into tertiary bronchi

Question 13

cardiac notch

Answer 13

a divit in the left lung that allows space for the heart

Question 14

how many lobes are in each lung (name them) and why

Answer 14

the right lung has 3 lobes -superior, middle, and inferior lobe - and the left had 2 - superior and inferior lobe- because the cardiac notch takes up too much room for there to be three lobes in the left lung

Question 15

bifricated into…

tertiary bronchi

Answer 15

bifricated into many terminal/respiratory bronchioles

Question 16

terminal/respiratory bronchioles

Answer 16

feed alveoli

Question 17

alveoli

Answer 17

where gas exchange occurs

Question 18

inhalation

Answer 18

breathing in

Question 19

phrenic nerve

Answer 19

causes diaphragm to move inferior

Question 20

(Inhalation) as thoratic cavity volume increases…

Answer 20

pressure decreases

boyle’s law
intrapulmonary pressure is now less than atmospheric pressure - so air wants to flow into the lungs

Question 21

Exhalation (passive)

Answer 21

breathing out

Question 22

(exhalation)throatic volume decreases

Answer 22

pressure increases

Boyle’s law
intrapulmonary pressure is now greater than atmospheric pressure - so air wants to flow out of the lungs

Question 23

during inhilation ribs move…

Answer 23

lateraly (bucket handle) and anterior to posterior (pump handle)

Question 24

parietal pleura

Answer 24

outer serous membrane of the lung

Question 25

viseral pleura

Answer 25

inner serous memebrane of the lung

Question 26

pleura cavity

Answer 26

space between serous membranes

Question 27

external respiration (lung/haldane)

Answer 27

O2 diffuses from alveoli into capillaries
CO2 diffuses from capillaries into alveoli

Question 28

internal Respiration (tissue/Bohr)

Answer 28

O2 diffuses from capillaries into tissue cells
CO2 diffuses from tissue cells into capillaries

Question 29

Bohr Effect

Answer 29

CO2 + H2O form carbonic Acid
-this dissociates into H+ & HCO3-
-the H+ increases the acidity of the blood causing oxygen to diassociate from hemoglobin

less CO2 less acidic

goal is to produce H+ ions to get oxygen

Question 30

Haldane Effect

Answer 30

in lungs
-inhaled oxygen binds to Hb, which releases H+
-carbonica anhydrase reaction now goes in rever forming CO2 to be exhaled

more CO2 is more acidic

goal is to produce CO2
