Webthe contraction of the diaphragm. true false out of the lungs, called expiration Inspiration begins with: As alveolar volume increases, alveolar pressure decreases. Air moves from areas of low pressure to areas of high pressure until an equilibrium is reached. Which way does air flow when alveolar pressure is greater than atmospheric pressure? WebThe diaphragm is a sheet of internal muscle which extends across the bottom of the rib cage. This is an important muscle that separates the thoracic cavity, which contains the heart, lungs and ribs, from the abdominal cavity. When we say ‘diaphragm’, we generally refer to the thoracic diaphragm that helps in breathing.
