☆ What is Respiratory system?

Respiratory system is  a catabolic  process (break down of food into  simple form)  and also biochemical process.It defined as ” Exchange of environmental oxygen into carbon dioxide take place between body and the outside complete environment.”

  • In other words we can say exchange of gases (viz. Oxygen and carbon dioxide) and oxidation of  food. is Respiratory system.


A process in which oxidation of organic compounds occurs in cell and energy is released is called as Respiration.”

Environmental Oxygen–>utilized by the organism———>to break down food ——–>Energy released ( by various activities in cells)———–>Carbon dioxide ( outer environment).

Hence,the process is  complete in the form of equation as :-

Food + Oxygen —> Carbon dioxide+ Water+ Energy
