The diaphragm moves down when you breathe in, so your lungs will expand to take in as much oxygen as possible.
When the diaphragm is down it creates a negative pressure and this causes the lungs to fill up and expand .
The diaphragm moves down to make the lungs expand (inhalation)
The diaphragm.
I believe that answer is the diaphragm. As the diaphragm moves up and down, it expands the lungs, and when the diaphragm goes up, the lungs release the air out again.
It is the thoracic diaphragm.
The diaphragm moves down to make the lungs expand (inhalation)
When you breath, your diaphragm moves up and down , causing air to flow into and out of the lungs .
the diaphragm
When the diaphragm moves down it is relaxing, causing the thoracic cavity to recoil. An increase in pressure causes the lungs to expel.
The opposite. When you exhale, the diaphragm moves upward to push the air out of the lungs.
Air moves into the lungs when the diaphragm is flattened. The diaphragm is relaxed (arched) during expiration.
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.
When you breathe out the diaphragm moves upwards to push the air out of the lungs. When you breathe in the diaphragm moves downwards to draw air into the lungs. When you breathe out your diaphragm contract and moves upwards towards your head. when you breathe in too much your diaphragm explodes
