Vocal organ has inferior vocal ligament responsible for phonation

Question 7

Epiglottis

Answer 7

Stops food and water from getting into lungs

Question 8

Tracheal cartilages

Answer 8

Get smaller as get closer to the lungs

Question 9

Primary bronchi

Answer 9

Branch into secondary bronchi (3 right lung, 2 left), branch into terchiary

Question 10

Secondary bronchi

Answer 10

Feed lobes of the lungs

Question 11

Terchiary bronchi

Answer 11

Feed bronchopulmonary segments

Question 12

Pulmonary arteries

Answer 12

Carry deoxy blood to lungs

Question 13

Pulmonary arteries

Answer 13

Carry oxy blood away from lungs

Question 14

Conducting zone contains

Answer 14

Trachea, bronchial tree, bronchioles, terminal bronchiols

Question 15

Conducting zone functions

Answer 15

Filter warm humtify and conduct air

Question 16

Respiratory zone contains

Answer 16

Respiratory bronchials, alvelolar sacs and ducts

Question 17

Respiatory zone functions

Answer 17

Gas exchange

Question 18

Emphysema

Answer 18

Elastic fibers give out. Can get air in easy but have to huff to get air out

Question 19

Asthma

Answer 19

Tonic constriction of bronchioles, small lumen that secrets lots of mucous

Question 20

B2 agonist/corticosteroid/combination therapy

Answer 20

Dialated bronchioles and reduce inflamation

Question 21

Elastic fibers and alveoli

Answer 21

Wrap around alveloi to help push air out

Question 22

Capillary beds and alveoli

Answer 22

Surround to help with gas exchange

Question 23

Visceral pleura

Answer 23

Single layer of cells that surrounds alveoli

Question 24

Partital pleura

Answer 24

Stuck on surface of diaphram

Question 25

Septal cells

Answer 25

Produce serphactin that mixes with water to increase surface area so lungs dont collapse

Question 26

Type I alveloi cells

Answer 26

Make up alvoli

Question 27

External resporation

Answer 27

Pulmonary ventilation, gas exchange at level of avelou and gas transport with oxy binding to hemoglobin

Question 28

Internal gas exchange

Answer 28

At level of capillaries and tissue

Question 29

Inspiration

Answer 29

Ribs move up and out, diaphram drops pulling praital membrane and visceral membrane widening alveoli creates vaccum air come in

Question 30

Exhalation

Answer 30

Ribs in and down, diaphram goes up pressure rises air flows out

Question 31

Inhalation graph

Answer 31

Pressure drops one causing air to flow in intrapleural pressure drops tital volume increases 500

Question 32

Exhalation graph

Answer 32

Pressure rises back up pressure goes back up 500ml out

Question 33

Sirus fluid

Answer 33

Sticks membranes together

Question 34

Must have negative pressure in pleural space

Answer 34

So lung doesnt collapse

Question 35

Resting tital volume

Answer 35

500ml

Question 36

Residual volume

Answer 36

Air you can never push out

Question 37

Expiratory reserve volume

Answer 37

Ab muscles used to push all air out

Question 38

Insipratory reserve volume

Answer 38

All air in

Question 39

Vital capacity

Answer 39

IRV+ERV+tital volume

Question 40

Gas exchange in pulmonary capillary

Answer 40

Gradients to exchange O2 from alveolus to blood and CO2 out of blood

Question 41

Po2 in blood in pulmonary cap

Answer 41

40

Question 42

Pco2 in blood in pulmonary cap

Answer 42

45

Question 43

Po2 in alveolus

Answer 43

100

Question 44

Pco2 in alveolus

Answer 44

40

Question 45

Po2 in blood in systemic cap

Answer 45

100

Question 46

Pco2 in blood in systemic cap

Answer 46

40

Question 47

Pco2 in tissue

Answer 47

45

Question 48

Po2 in tissue

Answer 48

40

Question 49

Oxygen hemoglobin saturation curve

Answer 49

In lungs heme is 100% saturated by oxy and as you move toward tissue it drops because unloading oxy to tissue

Question 50

Coolerativity

Answer 50

As o2 bind hem flexes and it makes binding effieity or the rest go up making it easy to bind

Question 51

Things cause right shift

Answer 51

Increase CO2, proton, temp, 23 BPG

Question 52

Left shift

Answer 52

Stonger binding for O2

Question 53

Tissue cell gas exchange

Answer 53

Dissolve CO2 causes HbCO2 and the bhor effect to push bicarbonate buffer to create more proton causes oxy to unload

Question 54

Pulmonary cap gas exchange

Answer 54

CO2 goes to alveoli and O2 comes in HbH causes more proton that shifts bicarbonate buffer left to produce CO2 and water
