The diaphragm is the main breathing muscle and separates the chest and abdominal cavities. During inhalation it contracts and moves downward, helping increase chest space. That anatomy does not establish that a specific breathing practice treats a health condition.

Text equivalent: During inhalation, diaphragm contraction helps enlarge chest space and air enters. During ordinary quiet exhalation, the muscles relax. The diagram does not measure an individual’s diaphragm function.

Clinical evidence relevant to diaphragm function
A worked situation: Between chest and abdomen
Fictional example. A learner follows an inhale on a simplified diagram: diaphragm contracts, chest space increases, and air enters the lungs. The sketch does not assess anyone's actual diaphragm function.
