  2. Respiration (physiology) - Wikipedia

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

    Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.

  3. 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 ...

  4. 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]

  5. Respiration - Wikipedia

    en.wikipedia.org/wiki/Respiration

    Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state; Respiration (physiology), transporting oxygen and carbon dioxide between cells and the external environment Respiratory system, the anatomical system of an organism used for respiration

  6. Biology - Wikipedia

    en.wikipedia.org/wiki/Biology

    Cellular respiration is a set of metabolic reactions and processes that take place in cells to convert chemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. [48] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy. Respiration ...

  7. Mouth-to-mouth resuscitation - Wikipedia

    en.wikipedia.org/wiki/Mouth-to-mouth_resuscitation

    It is used on a patient with a beating heart or as part of cardiopulmonary resuscitation (CPR) to achieve the internal respiration. Pulmonary ventilation (and hence external respiration) is achieved through manual insufflation of the lungs either by the rescuer blowing into the patient's lungs, or by using a mechanical device to do so.

  8. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    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 ...

  9. Anaerobic respiration - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_respiration

    Anaerobic cellular respiration and fermentation generate ATP in very different ways, and the terms should not be treated as synonyms. Cellular respiration (both aerobic and anaerobic) uses highly reduced chemical compounds such as NADH and FADH 2 (for example produced during glycolysis and the citric acid cycle) to establish an electrochemical gradient (often a proton gradient) across a membrane.
