When intraalveolar pressure exceeds atmospheric pressure what happens?
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 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 a pressure greater than atmospheric pressure is applied on pure water?
It is compressed and occupies a smaller volume.
What happens to air when it sink?
When a parcel of air is forced downward, atmospheric pressure increases, causing the air to become compressed and therefore the temperature is also raised.
What happens to atmospheric pressure as altitude increases?
As altitude increases, atmospheric pressure decreases.
What happens to carbon dioxide gas when it is compressed to high pressure and cooled to low temperatures?
Carbon Dioxide, under pressure and cooled, becomes 'Dry Ice'. It takes on the appearance of a block of frozen water (ice).
What happens to carbon dioxide in the blood when it flows through the capillaries in the alveoli?
The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.
What happens to the carbon dioxide in blood when it flows through the capillaries in the alveoli?
The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.
When intraalveolar pressure exceeds atmospheric pressure what happens?
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 the atmospheric pressure when weather is fair?
it dies
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 to cold air as it sinks?
As cold air sinks, it becomes denser and more compressed due to increased atmospheric pressure. This compression causes the air to warm up through the process of adiabatic compression.
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.
