When Air moves out of the lungs the pressure inside the lungs is?

when air moves out of the lungs, the air pressure decreases


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 happens when pressure is lower inside the lungs than outside the lungs?

When pressure inside the lungs is lower than outside, air flows into the lungs to equalize the pressure. This is known as inhalation, where the diaphragm contracts and the rib cage expands to create more space for air to enter the lungs.


Why does atmospheric pressure not crush our lungs?

Atmospheric pressure does not crush our lungs because the pressure inside our bodies is equal to the pressure outside. This balance allows our lungs to expand and contract without being crushed.


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.


Under what condition does air flow goes in to the lungs?

when pressure inside the lungs is lower then outer atmosphere


What effect does enlargement of the thoracic cavity has on the air pressure inside the lungs?

reduces intra-thoracic pressure which creates suction that draws air into lungs


If the pressure inside the lungs decreases outside air is pushed into the airways by what?

The pressure inside the lungs decreases as the ribcage moves out and up. Air from outside basically gets pushed in by other air molecules due to the pressure gradient (air moves from a high pressure to a low pressure)


What keeps the lungs from collapsing when the airways are open to the atmosphere?

The structure of the lungs, which are surrounded by a lining called the pleura, helps to keep them inflated. The pleural pressure is lower than the pressure inside the alveoli, creating a partial vacuum that prevents the lungs from collapsing. Additionally, the presence of surfactant in the alveoli reduces surface tension, helping to maintain lung expansion.


What transports air to the lungs?

AnswerAir is actually forced into the lungs by atmospheric pressure. But here's the rest of the story. The diaphragm, a muscle below the lungs, contracts and actually makes the space in which the lungs are located, the thorax, get bigger. When this space gets bigger, the pressure inside it decreases. There is now a difference in pressure between the lung cavity and the outside air with the outside air having more pressure. Air goes from where the pressure is higher to where it is lower, and so it goes into the lungs. That's called inspiration or inhaling. When the diaphragm relaxes, the thorax gets smaller and the pressure increases in the lungs and air is forced out. Click the link for more information.


What is Intrapulmonary pressure?

The intrapulmonary pressure is the pressure in the alveoli. Intrapulmonary pressure rises and falls with the phases of breathing, but it ALWAYS eventually equalizes with the atmospheric pressure.


How does air flow between neighboring alveoli?

You use the respirerotry system. To be precise when air is to be sucked in, the brain askes the lungs to expand, which naturally creates a low pressure inside the lungs. Similarly when the lungs are compressed the air inside is flushed out.
