GARCIA CABRERA, Lizet; RODRIGUEZ REYES, Oscar  e  RODRIGUEZ CARBALLOSA, Oscar Bernardo. Regulation of breathing: morphological and functional organization of its control system. MEDISAN [online]. 2011, vol.15, n.4, pp. 558-567. ISSN 1029-3019.

The regulating main function of the breathing system is to maintain the normal oxygen and carbon dioxide pressures, as well as the H+ or hydrogen ions concentration, which is achieving adapting the lung ventilation to the organic metabolic needs of consumption and production of both gases, respectively. In spite of the wide variations in the requirements of oxygen intake and of carbon dioxide elimination, the arterial pressures of both elements remain within very narrow margins due to a complex regulation of the lungs ventilation by means of certain control systems. As it is a very complicated topic and as there are now new knowledge on this respect, it was decided to describe in this brief work the general morphological and functional organization of the elements that form the control system of the normal human breathing function.

Palavras-chave : breathing; lung ventilation; oxygen; carbon dioxide; hydrogen ion; arterial pressure.
