When the chest cavity expands and the diaphragm contracts, it creates more space in the chest cavity. The pressure decreases, and pulls on the lungs. The lungs fill with air to compensate for the lost space from the expansion and contraction.

What organ expands to fill with air?
Lungs expand to fill with air. It is done during respiration.
What structure is primarily responsible for keeping us breathing?
the lungs fill with air because the diaphragm (a muscle that runs underneat the ribcage) moves and causes the lungs to inflate
What two organs that fill up with air when you inhale are the?
This one can be a tricky answer. It could be the lungs if you count them as two individual parts or it can be the lungs and aveoli which are the tiny air sacs within your lungs that also fill up with air when you breath.
What happens to lungs when you inhale?
what happens when you inhale is that air goes into your lungs and your lungs get bigger ...Actually, your diaphragm moves to expand the volume of your thoracic cavity, which pulls a partial vacuum on your lungs, causing them to expand FIRST...and THEN the partial vacuum created by your expanded lungs causes air to move into them. When you breath out, it causes the reverse to occur.
What human action causes the lungs to become filled with air?
breathing is the human action that causes the lungs to be filled with air.
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 is the definition to draw in breath?
To fill your lungs by sucking in air.
What gives your lungs room to fill up with air?
its the bronchiole
