Breathing is normally an unconscious, involuntary, automatic process. The pattern of motor stimuli during breathing can be divided into an inhalation stage and an exhalation stage. Inhalation shows a sudden, ramped increase in motor discharge to the respiratory muscles (and the pharyngeal constrictor muscles). [5]
Conscious breathing encompasses techniques directing awareness toward the breathing process, serving purposes from improving respiration to building mindfulness. In martial arts like tai chi and qigong , breathing exercises are said to strengthen diaphragm muscles and protect organs, with reverse breathing being a common method.
The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...
The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...
Edzard Ernst writes that breathwork (or 'rebirthing') is a form of alternative medicine first devised by Leonard Orr in the 1970s. [4] [inconsistent]Breathwork is the use of breathing techniques in order to achieve altered states of consciousness and to have a variety of effects on physical and mental well-being. [3]

Breathing (spiration [1] or ventilation) is the rhythmical process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.
Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration. In most fish , and a number of other aquatic animals (both vertebrates and invertebrates ), the respiratory system consists of gills , which are either partially or completely external organs, bathed in the ...
The technology is based on the physiologic vibration generated during the breathing process when flow of air distributing through the bronchial tree creates vibration of the bronchial tree walls and the lung parenchyma itself. Emitted vibration energy propagating through the lung parenchyma and the chest wall reaches the body surface where is ...
