the expansion and relaxation of your diaphram.
your diafram
breathing is the human action that causes the lungs to be filled with air.
I think you meant move air into the lungs. The muscle is the diaphragm.
Suction is the force that "draws" or pulls rather than "drive" air into the lungs.When the diaphragm muscle pulls down, and the ribs expand slightly, the lungs also expand which sucks air into them.(see related links below)
Your lungs are the reasons you body has Oxygen. In your lungs, we do produce mucus, which we cough up because of the cilia in our lungs. Smoking causes this cilia to not move the mucus out of your lungs which in turn causes problems.
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
The contraction of the diaphragm causes it to move down, increasing the volume of the thoracic cavity. This movement and volume change decrease the pressure in the lungs, and air rushes in.
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.
When your lungs move to bring in air and remove gases you are breathing.
Air moves into and out of a person's lungs through the process of inhalation and exhalation. During inhalation, the diaphragm and chest muscles contract, creating a vacuum that draws air into the lungs. During exhalation, the diaphragm and chest muscles relax, allowing air to be pushed out of the lungs.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
Contraction of the diaphragm muscle causes it to move back up. When the diaphragm contracts, it flattens and moves downwards, increasing the volume in the thoracic cavity. This action creates negative pressure, sucking air into the lungs.
