Q

what is the pleural cavity?

A

it is a potential space between the two layers of pleura (parietal and visceral)

22
Q

what is a pulmonary collapse?

A

it occurs when enough air enters the pleural cavity to break the surface tension between the two layers of pleura; the elasticity of the lungs causes them to collapse

23
Q

what is a pneumothorax?

A

entry of air into the pleural cavity from a penetrating wound to the thoracic wall or a rupture of a pulmonary lesion into the pleural cavity, which results in a collapsed lung

24
Q

what is hydrothorax?

A

accumulation of excess fluid in the pleural cavity, usually the result of fluid escape into the pleural cavity or pleural effusion

25
Q

what is a hemothorax?

A

accumulation of blood in the pleural cavity, usually the result of a chest wound,
usually a result of a laceration of an intercostal vessel or internal throacic vessel rather than laceration of the lung

26
Q

what are lines of pleural reflection?

A

abrupt changes in the direction of parietal pleura

27
Q

what are the three lines of pleural reflection?

A

sternal line of pleural reflection, costal line of pleural reflection, and vertebral line of pleural reflection

28
Q

where does the costal pleura become the mediastinal pleura anteriorly?

A

sternal line

29
Q

where does the costal pleura become the diaphragmatic pleura?

A

costal line

30
Q

where does the costal pleura become the mediastinal pleura posteriorly?

A

vertebral line

31
Q

what is the first branch point of the trachea?

A

left and right bronchi

32
Q

where does the trachea exist?

A

in the posterior mediastinum

33
Q

how can the right main bronchus (can also be called the primary bronchus) be classified?

A

wider, shorter, and runs more vertically than the left main bronchus

34
Q

what are the secondary bronchi?

A

they go to each lobe of the lungs

35
Q

what is another name for the tertiary bronchi?

A

segmental bronchi

36
Q

what are the tertiary/segmental bronchi going to?

A

the corresponding bronchopulomonary segments

37
Q

what do the tertiary/segmental bronchi branch into?

A

conducting bronchioles

38
Q

what do the bronchi/bronchus have that the bronchioles do not?

A

cartilage

39
Q

what do the conducting bronchioles branch into?

A

the terminal bronchioles

40
Q

what do the terminal bronchioles branch into?

A

the respiratory bronchioles

41
Q

what is another name for secondary bronchi?

A

lobar bronchi

42
Q

what are the respiratory bronchioles capable of?

A

gas exchange

43
Q

what do the respiratory bronchioles branch into?

A

alveolar ducts

44
Q

what do the alveolar ducts end at?

A

an alveolus, which is the functional unit of the lung

45
Q

What is the significance of the right main bronchus being more vertical, wider, and shorter than the left main bronchus?

A

it is going to be a common site for foreign body aspirations

46
Q

What is the first site that is capable of gas exchange?

A

the respiratory bronchioles (they arent the primary site, but they are the first site that it can finally take place)

47
Q

what is bronchial asthma?

A

a widespread narrowing of the airways produced by contraction of smooth muscle, edema of the mucosa and mucus in the lumen of the bronchi and bronchioles

48
Q

What is a bronchoscopy?

A

insertion of a bronchoscope into the trachea to visualize the main bronchi

49
Q

at the split of the main bronchi, what do we have?

A

a ridge that is called carina

50
Q

why are bronchopulmonary segments important?

A

they are clinically relevant if you want to take out just a piece/segment of a patient’s lung
