The diaphragm is a domeshaped muscle located at the base of the thoracic cavity. Its primary role is to facilitate breathing by contracting and relaxing. When it contracts, it moves downward, increasing the volume of the chest cavity and allowing the lungs to expand. Conversely, when it relaxes, it moves upward, reducing chest cavity volume and expelling air from the lungs. This mechanism is fundamental to the process of respiration and is essential for sustaining life.
Diaphragmatic breathing, also known as abdominal breathing, involves the diaphragm's full range of motion. This type of breathing is not only efficient but also helps in reducing stress and improving lung function. It is often recommended for patients with respiratory conditions, as it maximizes oxygen intake and minimizes the workload on the respiratory muscles.
