1

The inferior thoracic aperture is closed by the ________

diaphragm

2

What are the three spaces in the chest that make up the thoracic structures?

left pulmonary cavity, right pulmonary cavity, and mediastinum

3

In the thorax, the blood supply (aorta, vena cava), nerve supply (vagus nerve), thoracic duct and esophagus all penetrate the __________

diaphragm

4

The superior thoracic aperture has a lot of blood vessels due to vasculature to what three areas?

head, neck, upper extremities

5

________ results from compression of vasculature and nerve supply penetrating superior thoracic aperture

thoracic outlet syndrome

6

What does the independence of pulmonary cavities signify?

You can have problems on one side but still maintain respiration on the other.

7

What two structures are contained within the pulmonary cavities?

Lungs and pleural sacs

8

The space inside the pleural sac is called the _________ and is empty

pleural cavity

9

The _______ is space sandwiched in between pleura on both sides

Mediastinum

10

The ______ pleural lines the lung whereas the ______ lines the body wall

visceral, parietal

11

What is found within the pleural space?

A tiny bit of fluid that allows the lung to slide back and forth as it expands and deflates

12

True/False: It is necessary to have positive pressure inside the lung during inspiration

FALSE, negative pressure to draw air in passively

13

True/False: In COPD, airflow in is compromised

False, can get air in, but can't get it back out

14

The ___________ is where the parietal pleura extends further down than the inflated lung. The normal space is about 2 ribs.

costodiaphragmmatic recess

15

What kind of nerve is the phrenic nerve?

Somatic (that's why we can control breathing!) with some autonomic fibers

16

The phrenic nerve is found sandwiched in between what two structures?

Parietal pleura and fibrous pericardium

17

Phrenic nerve comes from what vertebral levels?

C3-C5 [C3,4,5 keeps the person alive!]

18

Posteriorly (paravertebrally), the lungs (visceral pleura) go to above vertebral level of ____ whereas the parietal pleura go to vertebral level of ___

10, 12

19

Anteriorly, when looking at mid-clavicular level, the lungs (visceral pleura) go to about vertebral level of ____ and the parietal pleura to ___

6, 8

20

If looking from a mid-axillary viewpoint, the lungs (visceral pleura) go to about vertebral level of ___ and the parietal pleura to ____

8, 10

21

True/False: The cardiac notch has pleura over it and the lung continues into it

FALSE - the lung does not continue into the cardiac notch (does have pleural however)

22

Why is it important that patient raises their arms for CXR?

to get scapula out of the way

23

If looking along parasternal line, the lungs (visceral pleural) go to vertebral level of about ___, whereas the parietal pleura go to vertebral level of _____

4, 6

24

________ are potential spaces which can fill with blood, air and water in pathological states.

Pleural Recesses

25

This area of the lung consists of mainly pulmonary arteries, bronchi and pulmonary veins but anything entering or leaving the lung could also be considered part of this.

The root

26

The point where the arteries, bronchi, and pulmonary veins enter the lung is the ______

hilum

27

Describe the differences in bronchi on each side of the hilum

On the left side. the primary bronchus enters. On the right side, the secondary bronchi for upper and lower lobes enter.

28

Describe where the phrenic and vagus run in respect to the hilum

The phrenic runs anterior to the hilium and the vagus runs posterior

29

How many secondary bronchi are there?

2 on right, 3 on left

30

_______ enter the lobe whereas ______ enter the bronchopulmonary segments

secondary bronchi, tertiary bronchi
