Your brain senses it to your diaphragm and rib muscles telling it to breathe.
You don't only "breath in air, and breath out air," You breath in Oxygen and let out Carbon Dioxide. Passes to the diaphragm and the lungs, inhale oxygen, it goes through your body, exhale Carbon Dioxide, From which the body has made when inhaled.
The respiratory system uses diffusion and the diaphragm to bring oxygen into the lungs and push carbon dioxide out of the lungs. When you breath in your diaphragm expands into a dome shape creating an area of decompression and the air is forced into your lungs filling the empty space. When breating out it is the opposite the diaphragm flattens and pushes the air out of the lungs. THe air mainly consists of carbon dioxide
the diaphragm works as any other skeletal muscle, its contraction leads to the increase of the thoracic cavity hence reducing the pressure in the thoracic cavity making air to fill the lungs
the diaphragm... ^_^
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
That would be the diaphragm.
Allows people to breath
its when your diaphragm spazzums and you use your diaphragm to breath so if you stop breathing (hold your breath) you should be just fine (:
When you breath, your diaphragm moves up and down , causing air to flow into and out of the lungs .
we breath in oxygen and breath out carbon dioxide.
It will push out, if you are breathing from the diaphragm.
When the diaphragm contracts the air is pushed out to the lungs and we breath. also when you project your voice you diaphragm rises causing you to take deeper breaths- this is why you breath more when you project your voice\sing etc
