If intraalveolar pressure exceeds atmospheric pressure, air will flow out of the lungs due to the pressure gradient. This process is known as exhalation or expiration. It allows the lungs to get rid of carbon dioxide and regulate the levels of gases in the body.

What happens to atmospheric pressure as altitude increase?
This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
What generally happens to atmospheric pressure on a windy day?
On a windy day atmospheric pressure decreases because the higher the wind velocity, the lower the air pressure, or atmospheric pressure. This is how chimneys work, the air that moves above the chimney causes low air pressure because of the high wind velocity compared the velocity of the air inside a house. The air inside the house goes towards the low air pressure and takes the smoke with it.
What happens when carbon dioxide is compressed to atmospheric pressure?
When carbon dioxide is compressed to atmospheric pressure, it becomes a supercritical fluid with properties of both gases and liquids. It is often used in industrial processes like extraction and as a solvent due to its unique properties.
What happens when the atmospheric pressure is greatest near the Earths surface?
When atmospheric pressure is greatest near the Earth's surface, it usually indicates stable and fair weather conditions. High pressure systems generally bring clear skies, low humidity, and light winds. This can lead to pleasant weather conditions in the area.
What happens to the atmospheric pressure as elevation increases?
The higher the altitude, the lower the pressure becomes. One way to think of this is that the lower levels of the atmosphere, near the surface, are being pressed down by the molecules stacked above them, all of them drawn by Earth's gravity. Similarly, water in the oceans exerts a higher pressure the deeper you dive. Also, at the higher levels of the atmosphere, it is easier for molecules of lighter gases to achieve enough velocity to fly off into space.
What happens when intraalveolar pressure exceeds atmostpheric pressure?
lung at rest
What happens to the intraalveolar pressure when the diaphragm contracts?
When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity. This leads to a decrease in intraalveolar pressure, causing air to flow in from the atmosphere to equalize the pressure, resulting in inhalation.
What happens to the atmospheric pressure when weather is fair?
it dies
Sublimation can occur because solids like liquids have a?
Sublimation can occur because solids have enough thermal energy to transition directly into a gas without passing through the liquid phase. This process happens when the vapor pressure of the solid exceeds the atmospheric pressure.
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
What happens as you move higher in the tropospere?
Atmospheric pressure falls
What happens when pressure in the lung is greater than atmospheric pressure?
If the pressure in the lung is greater than atmospheric pressure, air will flow out of the lungs in order to equalize the pressure. This is called exhalation or breathing out.
What happens to matter as it sublimes?
When matter sublimes, it transitions directly from a solid to a gas phase without passing through the liquid phase. This process occurs when the substance's vapor pressure at that given temperature exceeds the atmospheric pressure, leading to the solid molecules escaping into the gas phase.
What happens if the atmospheric pressure drops?
The wind blow in towards the low.
What will happens to us if we go seventeen meters underwater?
We will experience a pressure 2.7 times atmospheric pressure.
What happens to pressure if you increase the ATM?
If you increase the atmospheric pressure, the pressure will also increase. This is because atmospheric pressure is the pressure exerted by the weight of air above a certain point, so increasing the amount of air causes an increase in pressure.
What happens when a pressure greater than atmospheric pressure is applied on pure water?
It is compressed and occupies a smaller volume.
