Chest breathing
The chest breathing is a form of pulmonary ventilation ( ventilation ). It takes place by expanding or narrowing the chest using the intercostal muscles .
When you inhale ( inspiration ) , the outer intercostal muscles contract (contract). The ribs rise and turn outward around their longitudinal axis, thus expanding the chest. This creates an increased negative pressure , through which the elastic lung tissue expands and air can flow through the airways .
During exhalation ( exhalation ) , the muscles relax, causing the ribs to twist back and lower, and the lungs to contract again as the chest narrows. The lung volume shrinks and the air is squeezed out. Exhalation is supported by the inner intercostal muscles , which lower the ribs when they contract. With forced exhalation (forceful, intensified breathing, e.g. during illness, physical exertion, when speaking or singing), additional auxiliary breathing muscles are used.
In addition to this, there is another breathing technique , abdominal breathing . Usually both techniques are used unconsciously together, but can also be consciously reinforced.
