It is not possible to breathe effectively without the body making certain changes or movements. Breathing involves the diaphragm contracting and moving downward, which increases the space in the chest cavity, allowing the lungs to expand and fill with air. This process also involves the intercostal muscles between the ribs and other accessory muscles that facilitate inhalation and exhalation. These movements are necessary to draw oxygen into the lungs and expel carbon dioxide efficiently. Without these physical movements, the lungs would not expand properly, and gas exchange would be impaired, making breathing impossible or severely compromised.
Breathing is both an involuntary and voluntary process controlled by the nervous system, and although some voluntary control is possible (e.g., holding breath or deep breathing), the foundational mechanics involving the diaphragm and rib movements are essential for normal respiration.
In summary, breathing requires the coordinated movement of muscles and changes in the chest cavity and diaphragm; without these physiological changes, breathing cannot occur properly because the lungs cannot expand and contract to move air in and out.
