Final answer:
Deep breathing practices such as diaphragmatic breathing can indeed help to temporarily increase lung capacity by allowing fuller expansion of the lungs and more efficient gas exchange in the alveoli.
Step-by-step explanation:
True. Deep breathing practices, specifically diaphragmatic breathing, can help to increase lung capacity. By actively engaging the diaphragm during deep breathing, this muscle contracts and allows the lungs to expand more than they do during shallow, costal breathing.
When practicing deep breathing, inspiratory muscles like the neck's scalenes contract to lift the thoracic wall, thereby increasing lung volume. Additionally, as the radii of the alveoli decrease, pressure increases, necessitating a deep breath to fully reinflate the alveoli for optimal lung function.
It's important to note that, while deep breathing can increase lung capacity temporarily and improve the efficiency of gas exchange in the alveoli, consistent practice is needed for any long-term effects on lung function. Over time, this type of breathing exercise may also contribute to the overall health of the respiratory system.
