It decreases, and air goes into the lung passages. You inhale.

When a person exhales what happens to the diaphragm?
The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it. When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.
What happens to the abdomen during inspiration?
The diaphragm contracts and so your abdomen comes out during inspiration.
When the diaphragm contracts and forces the abdominal organs downward what happens to the respiratory system?
As the volume of space above the pulled down diaphragm increases, air rushes into the lungs and they inflate, bringing fresh oxygenated air into the respiratory system.
What happens when you breathe out air?
When you breathe in, your diaphragm contracts and is pushed upwards. Your lungs expand and fill with air. The pressure within your chest cavity increases, and the body goes through the gas exchange process, providing red blood cells with oxygen. The carbon dioxide within red blood cells is then transferred into the lungs, and is exhaled along with traces of oxygen and other substances within the air. The diaphragm relaxes, lungs deflate, and pressure within the chest decreases.
What happens when the diaphragm stops working?
There's more than one thing called a diaphragm, so what happens when it fails depends on which one you're thinking of.
What happens when intraalveolar pressure exceeds atmostpheric pressure?
lung at rest
What happens when the air pressure in your chest cavity when your diaphragm contracts?
It decreases, allowing air to flow in.
What happens to the diaphragm when a person breathes in?
It contracts (and moves downward).
How do you breathe using the diaphragm?
When you take a breath, the diaphragm contracts and when it does, it drops down. This increases the size of the thoracic cavity. Air pressure is now lower in it than outside. Air moves from a high pressure to a low pressure. Air rushes in and the reverse happens when the diaphragm relaxes.
What happens to the diaphragm exhalation?
When breathing in, or inhaling, the diaphragm contracts, or tightens. When exhaling, or breathing out, the diaphragm expands, or loosens.
When the diaphragm contracts what happens to the size of the chest cavity?
It increases.
What happens during exhalation the diaphragm?
When breathing in, or inhaling, the diaphragm contracts, or tightens. When exhaling, or breathing out, the diaphragm expands, or loosens.
When a person exhales what happens to the diaphragm?
The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it. When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.
When intraalveolar pressure exceeds atmospheric pressure what happens?
intrapleural pressure exceeds atmospheric pressure, but lungs don't collapse because intra-alveolar pressure increases, too (4 mmHg pressure gradient stays same)
What happens to the diaphragm when you inhale and when you exhale?
When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs.
What happens to the abdomen during inspiration?
The diaphragm contracts and so your abdomen comes out during inspiration.
What happens to the size of the thoracic cavity when the diaphragm contracts?
it gets smaller in size forcing the air out of the lungs
