  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

    The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, producing large amounts of energy (ATP). Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions.

  4. 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 ...

  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. Exhalation - Wikipedia

    en.wikipedia.org/wiki/Exhalation

    Studies indicate that there are numerous other sites within the brain that may be associated with voluntary expiration. The inferior portion of the primary motor cortex may be involved, specifically, in controlled exhalation. [9] Activity has also been seen within the supplementary motor area and the premotor cortex during voluntary respiration.
