1

In which lobe do you find the cardiac notch?

the LEFT superior lobe (anterior aspect)

2

What separates the lobes of the left lung?

oblique fissure separates the left lung into superior & inferior lobes

3

What fissure separates the superior and middle lobes of the R lung?

horizontal fissure

4

What fissure separates the middle and inferior lobes of the R lung?

oblique fissure (of the R lung)

5

What spaces do the inferior borders of the lungs enter when we inhale deeply?

the costomedistinal recess

the costodiaphragmatic recess

6

What are the 3 surfaces common to both lungs?

costal surface (opposes rib cage)

mediastinal surface (opposes mediastinum)

diaphragmatic surface (opposes diaphragm)

7

Where is the hilum located on both lungs?

on the mediastinal surface

8

Name the contents of the hilum of the lungs

pulmonary A
pulmonary V
main bronchi
pulmonary L (hanginging pleura)

9

Where is the main bronchi typically located in each hilum?

usually more posteroinferior (thickest walled structure containing cartilage in wall)

10

Compare the anterior & posterior borders of the lungs

the posterior border is taller & more columnar b/c is in back of thorax

11

Where can lung cancer originate and what nerves can it impact?

derive from actual lung tissue or from bronchi

can involve phrenic N, vagus N, & recurrent laryngeal N

can frequently metastasize to LNs in thorax

12

Pneumonectomy

removal of 1 lung

13

Lobectomy

removal of 1 lobe of 1 lung

14

Segmentectomy

remove specific bronchopulmonary segment of 1 lung (via lung resection)

*1 bronchopulmonary segment has its own N & blood supply

15

Parietal Pleura

adherent to thoracic wall, mediastinum & diaphragm

16

Visceral Pleura

adherent to LUNGS

17

Pleuritis

inflammation of pleura that produces roughness on lungs (makes breathing difficult)

18

pleural cavity

potential space btwn 2 layers of pleura w/ serous lubricating fluid that reduces friction & produces cohesion through surface tension

19

Pulmonary collapse

occurs when excess air into pleural cavity

breaks surface tension btwn 2 layers of pleura & elasticity of lungs causes collapse

20

Pneumothorax

entry of air into pleural cavity from penetrating wound to thoracic wall Or rupture of pulmonary lesion into pleural cavity

results in collapse of lung

21

Hydrothorax

accumulation of excess fluid in pleural cavity (fluid escape into pleural cavity or pleural effusion)

22

Hemothorax

accumulation of blood in pleural cavity resulting from chest wound (laceration of intercostal or internal thoracic vessel)

23

Name the lines of pleural reflection

sternal line (costal to mediastinal anteriorly)
costal line (costal to diaphragm)
vertebral line (costal to mediastinal posteriorly)

24

Which structure in the airways has C shaped cartilage?

Trachea

(bronchi have irregular cartilage & bronchioles do not have any cartilage)

25

Where is an inhaled foreign object more likely to be stuck?

in the R main bronchus

26

Where is the trachea located?

in the posterior mediastinum

27

What is the last division of bronchi before they switch to bronchioles?

Segmental bronchi

28

What are the 3 divisions of bronchioles?

Conducting bronchiole
Terminal bronchiole
Respiratory bronchiole

29

Describe the components of the airway (top to bottom)

main bronchus (primary)
lobar bronchus (secondary)
segmental bronchus (tertiary)
conducting bronchioles
terminal bronchiole
respiratory bronchiole
alveolar duct

30

What is the main distinction between bronchus & bronchiole?

Bronchus has cartilage in walls but bronchioles have NO CARTILAGE
