2. Maintenance respiration - Wikipedia

   en.wikipedia.org/wiki/Maintenance_respiration

   Maintenance respiration in plants refers to the amount of cellular respiration, measured by the carbon dioxide (CO 2) released or oxygen (O 2) consumed, during the generation of usable energy (mainly ATP, NADPH, and NADH) and metabolic intermediates used for (i) resynthesis of compounds that undergo renewal (turnover) in the normal process of metabolism (examples are enzymatic proteins ...

3. Respiration (physiology) - Wikipedia

   en.wikipedia.org/wiki/Respiration_(physiology)

   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 ...

4. Respiratory system - Wikipedia

   en.wikipedia.org/wiki/Respiratory_system

   The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...

5. Control of ventilation - Wikipedia

   en.wikipedia.org/wiki/Control_of_ventilation

   The control of ventilation is the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration refers to the utilization of oxygen and balancing of carbon dioxide by the body as a whole, or by individual cells in cellular respiration. [1]

6. Ventilation–perfusion coupling - Wikipedia

   en.wikipedia.org/wiki/Ventilation–perfusion...

   Ventilation (or breathing) is the air movement between the lungs and the atmospheric air, facilitating gas exchange. The air rushes into the lungs through inhalation (inspiration) and is pushed out through exhalation (expiration). [2] During ventilation, the air movement is generated by the air pressure gradient between the atmosphere and the ...

7. Cellular respiration - Wikipedia

   en.wikipedia.org/wiki/Cellular_respiration

   Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical ...

9. Breathing - Wikipedia

   en.wikipedia.org/wiki/Breathing

   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.
