Flashcards in Lec 1 - 5 - Respiratory Pulmonary Function and Structure Deck (56):
1

inhaled gas is 100 percent blank before reaching gas exchange area

humidified

2

primary barrier between inside body and outside environment; inhaled pathogens and irritants

host defense

3

air moving across vocal cords

vocalization

4

lung has no direct blank capacity, it just goes by pressure differences leading to air flow

movement

5

flow in the lung formula

flow = delta P / R

6

the role of respiratory system is o2 delivery but the system is controlled by blank

co2

7

Flow of oxygen formula

Vo2 = inspired ventilation and O2 - expired ventilation and O2

8

we dont need a high blood pressure to the lungs because lungs have blank

very low blood flow resistance

9

lung volume is blank percent tissue and blank percent blood

60, 40

10

nasal/oral passage have shear forces causing synthesis and release of blank

nitric oxide

11

NO blank the bronchial airways

vasodilates

12

scm, scalenes, external intercostals, diaphragm are blank muscles

inspiration

13

internal intercostals, abs, obliques are blank muscles

expiration

14

expiration is blank unless forced

passive

15

left lung is blank compared to right due to the blank

smaller, heart

16

parietal pleura is attached to blank which causes the lungs to actually expand and contract

chest wall

17

air between lungs

pneumothorax

18

stuff between visceral and parietal pleura so they dont stick together

surfactant

19

most blank is in upper airways

resistance

20

most blank is in lower airways

compliance/gas exchange

21

conducting airway is aka anatomic blank

dead space

22

air flow velocity blank as we go deeper into the respiratory tract

decreases

23

Inflammation of smooth muscle of airway

Asthma

24

Genetic respiratory disease that has to do with chloride channels and obstruction by mucus

Cystic fibrosus

25

These allow mucus to get out and be secreted in the lungs

Goblet cells

26

Cilia is 9 doublets of blank and the center is blank

Actin/atpase, 2 singlets

27

Type of epithelium of alveoli that is most of the alveolus and does gas exchange

Type 1

28

Type of epithelium that produces surfactant in alveoli cells

Type 2

29

Type 1 epithelium is converted to type 2 near blank

Birth

30

Alveoli vary in size, lose surface area, and lose septae in this disease

Emphysema

31

Developmental disease that decreases alveolar number

Congenital diaphragmatic hernia

32

Lung function peaks at this age

20-25

33

Large pulmonary vessles have blank

Smooth muscles

34

Bronchial circulation is blank not blank

Systemic, pulmonary

35

Capillaries totally wrap around the alveolus so the entire alveolus does blank

Gas exchange

36

Surfactant functions to blank

Decrease surface tension

37

Fluid in trachea and terminal bronchioles for mucus clearance

Periciliary fluid

38

Fluid in trachea and terminal bronchioles via goblet cells

Mucus

39

Fluid that lines epithelium and is antistick and decreases surface tension

Surfactant

40

Periciliary fluid is maintained by blank secretion and blank absorption

Chloride, sodium

41

Cells in bronchioles relating to mucus that serves a regenerative function

Clara cells

42

Surfactant is blank based

Lipid

43

High volume in lung leads to blank surface tension

High

44

Low volume of lung results in blank surface tension of surfactant

Low

45

3 functions of surfactant

Reduce work of breathing, prevent collapse/sticking, reduce surface tension

46

There are no blank between endothelial cells of lymphatic system

Tight junctions

47

Lymphatic system has flow in one direction due to blank

Valves

48

preganglionic and postganglionic fibers of ans to lungs are in blank

central nervous system

49

pain comes from blank

pleura not lung

50

important nerves for lung

superior cervical ganglion, phrenic nerve, vagus nerve

51

parasympathetic causes airway blank, blood vessel blank, and glandular blank

constriction, dilation, secretion

52

noradrenergic noncholinergic inhibitory innervation causes blank of lungs

relaxation

53

noradrenergic noncholinergic innervation causes blank of lungs

stimulatory

54

parasympathetic nt

ach

55

sympathetic nt

NE

56

ventilation is controlled by a central pattern generator and has input from the blank and blank

hypothalamus, amygdala
