your diafram
the expansion and relaxation of your diaphram.
breathing is the human action that causes the lungs to be filled with air.
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.
The use of a machine to move air. In medical terms, a machine to aid a person in breathing by moving air into and out of their lungs.
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)
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.
It's an air pressure situation. When you breathe into a person's mouth you are creating positive pressure in their lungs. You are INFLATING the lungs. When to take you mouth away, the lungs deflate and the air comes back out. Blow air into a balloon then, if you do not keep the opening sealed, the air comes back out. Same priciple.
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.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
