22
Q

surface of each lung is covered with a

A

visceral serous called the pulmonary or viseral pleura

23
Q

walls of the thoracic cavity are lined by

A

parietal pleura

24
Q

caused by decreased secretion of pleural fluid

A

Pleruisy

25
Q

pleural surfaces become dry and rough resulting in

A

friction and stabbing pain with each breath

26
Q

pleural may produce excessive amounts of fluid which exerts pressure on the

A

lungs

27
Q

all but the smallest branches have

A

reinforcing cartilages in their walls

28
Q

terminal bronchioles lead into

A

respiratory zone structures

29
Q

respiratory zone includes

A

respiratory bronchioles, alveolar ducts, alveolar sacs and alveoli

30
Q

only site of gas exchange

A

alveoli

31
Q

serve as conduits to and from the respiratory zone

A

conducting zone structures

32
Q

balance of the lung tissue

A

storma

33
Q

describe storma

A

mainly elastic connective tissue that allows the lungs to recoil passively as we exhale

34
Q

has gas flowing past on one side and blood flowing past on the other

A

respiratory membrane (air blood barrier)

35
Q

final line of defense for the respiratory system is in the

A

alveoli

36
Q

wander in and out of the alveoli picking up bacteria

A

alveolar macrophages

37
Q

another name of alveolar macrophages

A

dust cells

38
Q

coats the gas exposed alveolar surfaces and is very important in lung function

A

surfactant

39
Q

cornerstone of all energy producing chemical reactions in the body

A

cellular respiration

40
Q

cellular respiration occurs in all

A

body cells

41
Q

inspiratory muscles

A

diaphragm

external intercoastals

42
Q

when inspiratory muscles contract

A

the size of the thoracic cavity increases

43
Q

volume within the lungs

A

intrapulmonary volume

44
Q

intrapulmonary volume increases

A

the gases within the lungs spread out to fill the larger space

45
Q

decrease in the gas pressure results in

A

partial vaccum

46
Q

partial vaccum

A

pressure less than atmospheric pressure

47
Q

as intrapulmonary volume decreases

A

the gases inside the lungs are forced more closely together and the intrapulmonary pressure rises to a point higher than the atmospheric pressure

48
Q

pressure within the pleural space

A

intrapleural pressure

49
Q

intrapleural pressure is always

A

negative and is the major factor preventing collapse of the lungs

50
Q

if the intrapleural pressure becomes equal to the atmospheric pressure

A

the lungs immediately recoil completely and collapse

51
Q

lung collapse

A

atelecasis

52
Q

during atelecasis

A

lung is useless for ventilation

53
Q

presence of air in the intrapleural space, which disrupts the fluid bond between the pleurae is called

A

pneumothorax

54
Q

pneumothorax is reversed by

A

drawing air out of the intrapleural space with chest tubes
