1

The whipp and wasserman model are ____ models

Gas exchange models

2

The gas exchange models is between the ____, ____, and the ___ works together for normal output

Muscle, circulation, and ventilation

3

What happens If there any blocks along the gas exchange models?

It will impair the other systems as well to get back to normal with the other working hard to get it so

4

In perspective, there is a ____ reserve in the lungs and capacity to diffuse gases

High

5

The surface area of the lung is approximately ___

750 ft

6

What is viscera pleura?

The internal serous membrane initmately attached to the surface of each lung. It is insensitive to pain

7

What is parietal pleura(rough surface)?

The external membrane lining the internal surface (wall) of the the thoracic cavity.

8

____produces pleural fluid into the pleural space to coat the lungs

Parietal pleura

9

The pleural space is located between ___ and ____. It is a ___ space

The pleural space is located between parietal and visceral pleurae. It is a closed space

10

True or false. There is no communication between the right and left pleural spaces

True

11

___ lubricates the glide of lungs during expansion

Pleural fluid

12

____ is a layer of fluid located between the parietal and visceral pleurae in the pleural space

Pleural fluid

13

What lubricates the surface of the pleurae?

Pleural fluid

14

___ facilitates the movement of the lungs across the thoracic wall during inspiration and expiration

Pleural fluid

15

What is pneumothorax?

If air is introduced into the pleural space as a result of chest trauma (ex: knife wound) the coupling between the parietal pleura and visceral pleura may be broken, causing the lung to collapse

16

What is hemothorax?

If blood is introduced into the pleural space as a result of chest trauma, the coupling between the parietal pleura and visceral pleura may be broken, causing the lung to collapse

17

What is pleural effusion?

If fluid is introduced into the pleural space as a result of chest trauma, the coupling between the parietal pleura and visceral pleura may be broken, causing the lung to collapse

18

When are the lungs under slight negative pressure?

When it is conatined in a patent pleural space

19

What does negative pressure do to the lungs?

It keeps the lungs expanded

20

What happens if air is introduced into the lungs?

It normalizes pleural pressure to atmospheric pressure, then pressure increases, causing the lungs collapse

21

What is included the upper respiratory tract? (proximal to bifurcation, at the angle of louie)

- Nose
- Pharaynx
- Nasopharynx
- Larynx
- Trachea

22

What is the pressure of the lung/pleura?

755 mmHg

23

What is the atmospheric pressure of the air?

760 mmHg

24

The upper tract is the ____ and ____ of air entering the lungs

The upper tract is the first line of filter and humidifier of air entering the lungs

25

The lungs prefer ___ air. ___ air creates brochiospasms and secretions in the lungs

The lungs prefer warm, moist and clean air. Cold air creates brochiospasms and secretions in the lungs

26

___ prevents food from entering the respiratory tract

Epiglottis

27

What is phonation?

Movement of air across vocal cords

28

Where does phonation occur?

In the laryngeal vocal cord

29

How does pulmonary disease affect phonation?

It lowers the tone and pitch, because less air is moving over the vocal cords

30

What is ventilation?

The movement of gas (conducting airways)
