firstly the intraplural cavity is a closed space and pressure change is due to increased volume. For example with the contraction of the diaphram causing the intraplural cavity to increase in size and therefore reducing the pressure causing inspiration. Since the intraplural space is attached to the lungs, the lungs also expands, theoretically increasing space and therefore reducing volume. So if the intraplural pressure down, lung pressure will also go down and vise versa with exhilation. hope that helps.

What happens if the air pressure in the throat and outside is less than the air pressure in your middle ear when you swallow?
if the aie pressure in the throat and outside the body is less than the air pressure in your middle ear when you swallow the air pressure in your middle ear reaches the same pressure as the air in your throat and outside , and the eardrum moves quickly back-or'pops' into place
What effect does vasodilation have on blood pressure?
Vasodilation typically leads to a decrease in blood pressure. This is because when blood vessels dilate, their diameter increases, allowing more blood to flow through them with less resistance, reducing the pressure on the vessel walls.
What is the name of the pressure that must be exerted on a solution to prevent the passage of solvent molecules into a solution when the solution and solvent are separated by a semipermeable membrane?
That pressure is called osmotic pressure. It is the pressure needed to prevent the flow of solvent molecules from a less concentrated solution to a more concentrated solution through a semipermeable membrane.
At which ocean feature would the most amount of pressure be exerted?
Water pressure increases with depth, so the deepest spot in the ocean is probably the location of the greatest water pressure. The Marianas trench is the deepest place (10,911m) and the pressure is 108.6 MPa. For a comparason, the standard sea-level air pressure is only 101.325 kPa, or about 1000 less.
Starvation causes the plasma protein levels in the blood plasme to fall how would that affect the formation of tissue fluid in the tissue spaces?
Starvation causes the plasma protein levels to decrease, and when there is less plasma protein in the blood, you get lower Po (Osmotic Pressure). Lower osmotic pressure means less pull (of tissue fluid) so this causes generalized edema.so basically, less plasma proteins -> decreased Po -> less pull -> reduced venous clearance --> fluid build up in tissue
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure is the pressure inside the lung alveoli, while intrapleural pressure is the pressure in the pleural cavity. During normal breathing, intrapleural pressure is lower than intrapulmonary pressure, creating a pressure gradient that helps keep the lungs inflated.
Is intrapleural pressure 4 mm Hg less than the pressure in the alveoli?
true.
Is intrapulmonary pressure greater than or less than?
Yes, typically it is.
What is the intrathoracic pressure?
Negative intrathoracic pressure is the normal pressure in the area between the pleura of the lungs and the chest wall. The pressure is considered negative because it is less than the atmospheric pressure.
Is pressure after throttling is more or less?
You cannot increase steam pressure through a valve without adding heat to it. Throttling steam always reduces its pressure.
What is the correct tire pressure for a 2008 Chevy suburban?
The correct tire pressure depends on the tire. The max pressure will be listed on the sidewall of the tire. I usually run about 5lbs less than the max. Always check your tire pressure when the tires are cold.
What is efficiency always less than?
It is always less than 1 or 100%.It is always less than 1 or 100%.It is always less than 1 or 100%.It is always less than 1 or 100%.
A pressure reading less than atmospheric pressure is?
Low pressure
If the weather forecaster tells you that the pressure is falling what is the air density doing?
They tell you exactly the pressure is falling when the density of the air around us gets less, this means that air from other area's will be moving toward us to fill the air pressure up, air always moves from a high pressure area to a lower pressure area
Weather element that always decreases with increasing height?
Pressure always decreases with height. This is because atmospheric pressure is just a measure of how much air is weighing down. So the higher you go in the atmosphere, the less air is above you (more of it is below you) and the lower the pressure will be.
What does a low pressure area?
It has less air pressure than the surroundings.
How does pressure change with height?
When you get into higher altitudes, there are less molecules. Making the pressure less dense. It also has less oxygen molecule, making it harder to breathe.
