The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the...

∙ 14y agoWhen our diaphragm contracts and moves down and our intercostal muscles contract causing our lungs to move out and up, there is a pressure change in the thorax. This means that air from the atmosphere must quickly rush in to our lungs to regulate the pressure. This is how we breathe in.
The same happens in opposite when we exhale.

∙ 11y agoI guess oxygen come from the trees since they're moist. Then when you open your mouth and breathe in, your tonsils suck the air in and when you breathe out, you're getting that air out and resucking new air. I guess that's how to explain it, if you think about it.

When Air moves out of the lungs the pressure inside the lungs is?
when air moves out of the lungs, the air pressure decreases
Air moves from the outside into the lungs through?
The air moves from the outside into the lungs through the windpipe.
What happens in the lungs when you breathe out air?
the lungs will moves down when breathe out air
What moves air in and out the lungs?
the diaphragm
How air moves into and out the lungs?
breathing.
What force cause air to move in an out of the lungs?
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
When air moves into the lungs when the diaphragm muscles do what?
The diaphragm moves down to make the lungs expand (inhalation)
Air moves into the lungs when the diaphram muscle?
Air moves into the lungs when the diaphragm is flattened. The diaphragm is relaxed (arched) during expiration.
The diaphragm moves air into and out of the what of a mammal?
Lungs.
Identify how air moves into and out of the lungs?

What happens when the diaphragm moves downward and the rib cage moves up and out?
The opposite. When you exhale, the diaphragm moves upward to push the air out of the lungs.
What muscle works with the lungs and ribs to get air in and waste gases out of the lungs?
The muscle is the "diaphragm" muscle. It is located beneath the lungs. When it moves down and away, it creates lower pressure around the lungs, and the air pressure outside the body flows into the lungs. When it moves up and in, it compresses the lungs, increasing the pressure to force the air back out.
