Answer: In deep breathing, the diaphragm muscle contracts to allow more space for the lungs to fill with air.

Deep breathing technique refers to a long slow breaths that are carried through the diaphragm muscle. The diaphragm’s contraction pulls it all the way the down, allowing the lungs to inhale more air during its expansion. The active process of oxygen and also carbon dioxide exchange occurs when a person inhales and then exhales deeply. The blood contains much more oxygen and this leads to many things such as low blood pressure and also heart rate since the body is now getting relaxed. Besides, deep breathing causes the abdominal muscles to expand rather than the chest thus creating more room for the lungs. It prolongs the focus through the supplying the more oxygen to the brain . In the end, the contracting diaphragm makes the lungs fill with the air during the long but slow breathes thus giving both mental and also physical benefits.
