Schematic drawing of a lung-on-a-chip. The membrane in the middle can be stretched by vacuum in the two side chambers. Lung-on-a-chip (LoC), also known as Lung Chips, are micro- and millifluidic organ-on-a-chip devices designed to replicate the structure and function of the human lung, mimicking the breathing motions and fluid dynamics that occur during inhalation and exhalation.

This compresses the abdominal cavity, raises the ribs upward and outward and thus expands the thoracic cavity. This expansion draws air into the lungs. When the diaphragm relaxes, elastic recoil of the lungs causes the thoracic cavity to contract, forcing air out of the lungs, and returning to its dome-shape. [1]
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 ...
Real-time magnetic resonance imaging of the human thorax during breathing X-ray video of a female American alligator while breathing. 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.
Fire breather’s pneumonia is caused by the entrance of hydrocarbon fuels into the bronchial tree, usually due to accidental aspiration or inhalation during a fire performance show. Fire breathing, or fire blowing, is the act of creating a plume of fire by blowing a mouthful of fuel in a fine mist (atomization) over a source of ignition. Fire ...
Shallow breathing, thoracic breathing, costal breathing or chest breathing [1] is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be symptomatic of rapid breathing and hypoventilation ...

Fire breathing has a wider range of risks due to the required technique to create the effect. Having an actively spotting trained safety assistant with an appropriate fire blanket and fire extinguisher is an appropriate best practice when fire breathing and is a mandatory clause in most insurance policies for professional fire breathers.
