Respiration is a catabolic process involving: the burning of food substances in the presence of oxygen, elimination of carbon dioxide produced during the oxidation and the release of energy. Some of the energy is stored in the high energy bonds of ATP molecules. The respiratory system consists of respiratory organs and respiratory tracts. On the basis of types of respiratory organs, there are following modes of respiration: skin respiration, buccopharyngeal respiration, tracheal respiration, branchial respiration, and lungs/pulmonary respiration. The respiratory tract is the path for fresh and foul air where no gaseous exchange occurs. The respiratory tract comprises the following parts: nostril, nasal chamber, internal nares, pharynx, larynx, trachea, bronchi, and a respiratory organ.
