The first thing that happens to most people is called high altitude pulmonary edema, a build up of fluid in the lungs that makes it hard for them to breathe. In very susceptible individuals this can happen at as low as 1500 meters above sea level (air pressure around 85 kPa).
At partial pressures of oxygen less than about 10 kPa, your lungs can no longer efficiently absorb oxygen from the air. If you're breathing normal air, this happens at an overall pressure of around 50 kPa, corresponding to a height of about 6 km above sea level.
Should the overall air pressure drop below around 10 kPa (normal atmospheric pressure is around 100 kPa and the pressure at the top of Mount Everest is around 30 kPa), water evaporation would become significant. By the time the pressure dropped to 6 kPa, all the moisture in your body would be evaporating so fast it would literally be boiling.

What happens to the air molecules in a divers lungs as the pressure increases during a dive?
As the diver descends deeper into the water, the pressure increases. This causes the air molecules in the diver's lungs to compress, leading to a decrease in volume. In order to maintain equilibrium with the increasing pressure, the air molecules in the lungs will be forced into smaller spaces, potentially causing discomfort or injury if not managed properly through controlled breathing techniques.
What causes the air pressure in your lungs to decrease and make you inhale?
When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
What happens to air pressure when the temperature changes?
air pressure becomes less in cold tempuratures
Does air pressure decrease at night?
It is not a rule.
When you inhale does pressure decrease inside or increase?
The act of inhaling is to create low pressure in the lungs, causing the air in the atmosphere to rush in as it is moving from a higher pressure (outside in the atmosphere) to the lower pressure (created in the lungs). However the fact that air does move into the lungs means that there is no net change in pressure.
Why does the lung collapse if intrapleural pressure is not maintain?
Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.

What muscle allows the lungs to fill the lungs with air?
The diaphragm. (located beneath the lungs) When it contracts it moves down, thus expanding the volume of the lungs. This causes the pressure in the lungs to decrease and air to flow in to the lungs. (pressure is inversely proportional volume- Boyle's law) This is inhaling. When the diaphragm relaxes it moves back up, decreasing the volume of the lungs and increasing the pressure which forces the air out. This is exhalation.
What happens when you decrease mass in a given volume of air?
The temperature and pressure rise.
When air gets warmer what happens to the air pressure?
The air pressure will increase when the sky is clear and the sun is out, and will decrease during storms or poor weather.
What happens to air pressure when air gets warmer?
The air pressure will increase when the sky is clear and the sun is out, and will decrease during storms or poor weather.
When Air moves out of the lungs the pressure inside the lungs is?
when air moves out of the lungs, the air pressure decreases
A scuba diver is working on the ocean floor he takes a big breath and swims to the surface what happends to the air in his lungs?
As he rises , the air in his lungs expands due to a decrease in pressure. If not allowed to exit, his lungs will explode.
What happens to air pressure as you move away from earths surface?
it decrease and it is globel warming
What happens to pressure at different temperatures?
Pressure (such as air in a balloon) can increase with higher temps and decrease with lower temps.
What causes the air pressure in your lungs to decrease and make you inhale?
When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
