What is the difference between Intrapulmonary and Intrapleural?
Transpulmonary pressure
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure will equalize to atmospheric pressure during a breathing cycle, but intrapleural pressure should always be less than atmospheric pressure.
Show a diagram that shows how air has weight?
it would be very hard to draw but if you draw 2 ballons one with air and one with no air then see which ones heavier it has to be the ballon filled with air
What is the characteristic of air?
Air have mass and space,these characteristic
Why is there no sound in the vacuum of space?
Because sound travells by air and if there is no air then sound cannot travel to your ears. A vacum is where there is no air e.g. space.
A chest wound can introduce air into the intrapleural space a condition known as?
The term that describes the result from an injury that permits air to leak into the intrapleural space is pneumothorax
What is the intrapleural space?
the intrapleural space is also referred to as the intrapleural cavity - the space where the major organs are fitted into and protected by the surrounding skeletal rib cage.
What is the intrapleural?
the intrapleural space is also referred to as the intrapleural cavity - the space where the major organs are fitted into and protected by the surrounding skeletal rib cage.
If air enters the intrapleural space?
The lung will collapse (atelectasis) because the negative intrapleural pressure gradient that keeps the lung inflated has is now at equilibrium with atmospheric pressure.
Equilibration of pressure between the intrapleural space and the alveoli will lead to?
A pneumothorax, or a collapsed lung.
What would be the effect of a pneumothorax (air in the intrapleural space) on the lungs and breathing?
The affected lung would collapse or not be able to expand fully, so lung ventilation would decrease.
What attaches the lungs to the inner chest wall?
The answer is a vacuum. It is called the intrapleural space and is the negative pressure inside the thoracic cavity between the visceral pleura and the parietal pleura. When a person looses this pressure due to an injury and air comes into this space, they are said to have a collapsed lung.
When is intrapleural pressure most negative?
Intrapleural pressure is most negative at the completion of inspiration.
What pressure keeps lungs inflated?
Intrathoracic pressure
How is intrapleural pressure maintained?
Intrapleural pressure is the pressure difference between the lungs and the pleural cavity of the lungs.
What conclusion can you draw about the makeup of space?
the characteristic of styrofoam and hydrophilic polymers. the enables them to hold air or water is
Explain the functional importance of the partial vacuum that exists in the intrapleural space?
If not present (and the intra-alveolar pressure equaled atmospheric pressure) the lungs would collapse.
