The muscle is the diaphram and it is located just beneath your lungs.
When you inhale your rib muscle and diaphram contract and expand the chest cavitie. When you exhale you rib muscle and diaphram relax, reducing the size of the chest cavitie.
Your diaphragm IS muscle. When we inhale, it is pushed down. When we exhale, it is pulled up.
The Diaphram
Passive means passive - no muscle action is necessary. You must use your muscles to inhale ... and you can use them to speed up exhalation.
No, as you inhale the diaphragm is contracting and pulling down, expanding the lungs. As you breathe out, the muscle relaxes and rises up again.
The thin sheet of muscle is called the diaphragm. It relaxes and contracts to help us inhale and exhale.
Inhale
diaphragm
when you inhale..(take in oxygen)..the air fills up the lungs, the ribcage expands and the muscle sheet called the diaphragm pushes downward and flattens as you inhale ..whn you ehale the muscle returns back to domed-shape
the teacher said "calm down and inhale slowly. One, two. One, two".
The action is the flattening of your diaphragm, or the muscle that helps your lungs inhale and exhale.
