Pleural fluid is in the ____
What does the fluid do?

Answer 10

In pleural space (between parietal and visceral pleura)
It lubricates gliding movements of lungs

Question 11

pleural fluid surface tensions keeps ____ ____

Answer 11

Keeps lungs open
Negative pressure keeps lungs inflated

Question 12

Pneumothorax?

Answer 12

Air in chest cavity

Question 13

Pleural recesses

Answer 13

Answer 17

Trachea
Primary bronchi
Secondary bronchi
Tertiary bronchi

Question 18

Hilum of lung: how many different blood supplies

Answer 18

Two
Pulmonary arteries/veins (alveoli)
Bronchial arteries/veins (bronchial tree)

Question 19

Innervation of the lungs (parasympathetic)

Answer 19

Bronchoconstriction
Gland secretion

Question 20

Innervation of the lung (sympathetic)

Answer 20

Bronchodilation

Question 21

Boyle’s law

Answer 21

Pressure varies inversely with volume

Question 22

Inspiration

Answer 22

Inhale
Diaphragm contracts
Thoracic wall gets bigger

Question 23

Accessory respiratory muscles

Answer 23

Intercostal muscles
Scalene muscles
Sternocleidomastoid
Serratus anterior

Question 24

Expiration

Answer 24

Breathe out
Diaphragm relaxes
Thoracic walls gets smaller

Question 25

Inspiration alveoli

Answer 25

Alveoli and airways get bigger and the elastic tissue stretches

Question 26

Expiration alveoli

Answer 26

Relaxation of elastic tissue recoils alveoli and airways go back to resting position

Question 27

Inspiration Boyle’s law

Answer 27

Volume increases Pressure decreases Lungs expand

Question 28

Expiration Boyle’s law

Answer 28

Volume decreases Pressure increases Lungs shrink

Question 29

Answer 29

2 Right lungs: 3 lobes, 3 2° bronchi

Answer 30

Question 31

label: respiratory bronchiole alveolar duct terminal bronchiole

Answer 31

Question 32

where is the respiratory zone?

Answer 32

Question 33

where is the conducting zone?

Answer 33

Question 34

difference between bronchus and bronchiole?

Answer 34

bronchus: cartilage

Question 35

Answer 35

Question 36

trachea

Answer 36

Question 37

1° right and left bronchus

Answer 37

Question 38

Answer 41

Question 42

Answer 42

3

Question 43

Answer 43

Question 44

does the diaphragm move up or down during contraction?

Answer 44

down

Question 45

does the diaphragm move up or down during relaxation?

Answer 45

up

Question 46

does thoracic volume inc/dec when relaxed? does thoracic volume inc/dec when contracted?

Answer 46

relaxed diaphragm (up): decrease in volume contracted diaphragm (down): increase in volume

Question 47

Answer 47

phrenic nerve (C3-5)

Question 48

what nerve innervates the diaphragm?

Answer 48

phrenic nerve (C3-5)

Question 49

Answer 49

visceral pleura * to the left (dark space) is the pneumothorax (air in chest cavity - pleural space)

Question 50

Answer 50

R 2° bronchus (inferior lobe)

Question 51

Answer 51

VAGUS parasympathetic --> bronchoconstriction parasympathetic nerve is VAGUS Blocking the vagus nerve will stop parasymp from causing bronchoconstriction and open airways
