Inhalation of air, as part of the cycle of breathing, is a vital process for all human life.The process is autonomic (though there are exceptions in some disease states) and does not need conscious control or effort.
In physiology, respiration is the transport of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the environment by a respiratory system.
Bioinspiration is a solidly established strategy in the field of chemistry, but it is not a mainstream approach.Especially, this research is still developing its scientific and technological systems, on academic and industrial levels.
Aerobic respiration requires oxygen (O 2) in order to create ATP.Although carbohydrates, fats and proteins are consumed as reactants, aerobic respiration is the preferred method of pyruvate production in glycolysis, and requires pyruvate be transported the mitochondria in order to be oxidized by the citric acid cycle.
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.
Ventilation is normally unconscious and automatic, but can be overridden by conscious alternative patterns. [3] Thus the emotions can cause yawning, laughing, sighing (etc.), social communication causes speech, song and whistling, while entirely voluntary overrides are used to blow out candles, and breath holding (for instance, to swim underwater).
In biology, a mechanism is a system of causally interacting parts and processes that produce one or more effects. [1] Phenomena can be explained by describing their mechanisms. For example, natural selection is a mechanism of evolution ; other mechanisms of evolution include genetic drift , mutation , and gene flow .
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
