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.

Animation of diaphragmatic breathing with the diaphragm shown in green. Diaphragmatic breathing, abdominal breathing, belly breathing, [1] or deep breathing, [2] is breathing that is done by contracting the diaphragm, a muscle located horizontally between the thoracic cavity and abdominal cavity.
Here are some key words used throughout the article. The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand.
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.
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 ...
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 ...

The lungs expand and contract during the breathing cycle, drawing air in and out of the lungs. The volume of air moved in or out of the lungs under normal resting circumstances (the resting tidal volume of about 500 ml), and volumes moved during maximally forced inhalation and maximally forced exhalation are measured in humans by spirometry.
