eli5 Why do our stomachs move when we breathe?
In: Biology
Air moves into lower pressure environments, so when you try to take a breath, your diaphragm flexes into your stomach area to create a low pressure vacuum in your lungs. Air is drawn through the nostrils or mouth into the constricted windpipe, and down into the bronchioli of your lungs. Oxygen enriches the blood, and is converted into carbon dioxide. Then your diaphragm flexes the alternate direction, squeezing your inflated lungs against your ribcage and raising the pressure in your lungs. When your windpipe opens, the pressure is released from your lungs. Exhale.
