Flashcards in Test 3 week 5 Deck (229)
The whipp and wasserman model are ____ models
Gas exchange models
The gas exchange models is between the ____, ____, and the ___ works together for normal output
Muscle, circulation, and ventilation
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
In perspective, there is a ____ reserve in the lungs and capacity to diffuse gases
The surface area of the lung is approximately ___
What is viscera pleura?
The internal serous membrane initmately attached to the surface of each lung. It is insensitive to pain
What is parietal pleura(rough surface)?
The external membrane lining the internal surface (wall) of the the thoracic cavity.
____produces pleural fluid into the pleural space to coat the lungs
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
True or false. There is no communication between the right and left pleural spaces
___ lubricates the glide of lungs during expansion
____ is a layer of fluid located between the parietal and visceral pleurae in the pleural space
What lubricates the surface of the pleurae?
___ facilitates the movement of the lungs across the thoracic wall during inspiration and expiration
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
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
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
When are the lungs under slight negative pressure?
When it is conatined in a patent pleural space
What does negative pressure do to the lungs?
It keeps the lungs expanded
What happens if air is introduced into the lungs?
It normalizes pleural pressure to atmospheric pressure, then pressure increases, causing the lungs collapse
What is included the upper respiratory tract? (proximal to bifurcation, at the angle of louie)
What is the pressure of the lung/pleura?
What is the atmospheric pressure of the air?
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
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
___ prevents food from entering the respiratory tract
What is phonation?
Movement of air across vocal cords
Where does phonation occur?
In the laryngeal vocal cord
How does pulmonary disease affect phonation?
It lowers the tone and pitch, because less air is moving over the vocal cords
