The major function of the respiratory system is to obtain oxygen and remove carbon dioxide for metabolic processes in the body. The aerobic metabolic pathway of conversion of nutrients to energy requires oxygen, for example:<\/p>\r\n

C6<\/sub>H12<\/sub>O6<\/sub>\u00a0+ O2<\/sub>\u00a0\u2192 CO2<\/sub>\u00a0+\u00a06<\/sub>H2<\/sub>O + energy as ATP<\/p>\r\n

So, for each molecule of glucose that is converted to energy, a molecule of oxygen is needed. Because the cells require a continuous supply of ATP, the body, in turn, needs a constant intake of oxygen and method for removal of carbon dioxide. Our respiratory system functions to accomplish these necessary gas exchanges.<\/p>\r\n
