Breathing, also known as respiration, is the biological process of taking in oxygen from the environment and expelling carbon dioxide from the body. The respiratory system, consisting of the nasal or oral cavity, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli, facilitates the exchange of gases. Air enters through the nose or mouth, travels down the trachea, and is distributed in the lungs where alveolar membranes allow oxygen to diffuse into the bloodstream and carbon dioxide to move into the alveolar space for exhalation.
The mechanics of breathing involve two primary phases: inhalation (inspiration) and exhalation (expiration). During inspiration, the
Pneumostasis, the regulation of breathing rate and depth, is controlled by the medulla oblongata in response
Breathing techniques, such as diaphragmatic breathing or paced respiration, are employed in various health interventions to
