Your brain senses it to your diaphragm and rib muscles telling it to breathe.
When carbon dioxide accumulates in the body, it can lead to an increase in acidity, which stimulates chemoreceptors in the brain to signal the diaphragm and other respiratory muscles to increase breathing rate and depth. This response helps to remove excess carbon dioxide from the body and restore its acid-base balance.
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... ^_^
Holding your breath increases levels of carbon dioxide in your body, which signals the brain to trigger the urge to breathe. Receptors in the body called chemoreceptors sense the changes in carbon dioxide levels and send signals to the brainstem, prompting it to initiate breathing.
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
Allows people to breath
That would be the diaphragm.
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 .
It will push out, if you are breathing from the diaphragm.
The diaphragm ( the muscle underneath your lungs that help you breath) is a skeletal muscle, not smooth
