Air rushes into the lungs of humans during inhalation

Last updated: 7/19/2022

Air rushes into the lungs of humans during inhalation because a positive respiratory pressure is created when the diaphragm relaxes. gas flows from a region of lower pressure to a region of higher pressure. pulmonary muscles contract and push on the outer surface of the lungs. the volume of the alveoli increases as smooth muscles contract. the rib muscles and diaphragm contract, increasing the lung volume.
