WebAssessment of diaphragm function begins with the physical examination, but neither the physical examination nor radiography is sensitive enough to detect subtle abnormalities of diaphragm function. WebPhysiology of Respiration: Ventilation: The process of breathing involves taking in oxygen and releasing carbon dioxide from the lungs. Air flows into and out of the alveoli, or tiny air sacs in the lungs, during this initial stage of breathing. When the diaphragm contracts and relaxes, air is sucked in, allowing it to enter and exit the lungs.
