Respiration is a process which provides body with oxygen for growth and other metabolic activities and removes waste products in the form of carbon dioxide gas. The exchange of gases take place in the Lungs. The Lungs are the main organs involved in the respiration process. Air passes into the lungs through the process of inhalation through the nostrils and the air flows down the trachea into the lungs. The Lungs have alveoli which are small air sacs and  is filled with tiny capillaries which are functional in the carrying of oxygen and carbondioxide back and forth from the heart to the lungs. Respiration process in plants and animals takes place differently thought he main goal is similar.  The organs of respiration are different in living organisms based on their evolution, Some respire through skin such as earthworm, fish use gills while whales use both gills and lungs like mammals.  Since the process occurs inside the cells, it is also called as cellular respiration. During this process, carbohydrates mainly the glucose is broken down and energy(ATP) is released. This energy is used by the cells for various functions and processes from muscle contraction to cell building, repair and growth.

Respiration is a vital process which occurs in all living organisms. It is a chemical process in which glucose is broken down for carrying of life processes. The chemical reaction which involves respiration is as follows:
                C₆H₁₂O₆ + 6O₂ -----------> 6CO₂ + 6H₂O + energy

The glucose is broken down into Carbon Dioxide, water and energy. The energy is converted into a chemical energy in the form of ATP. This ATP helps to provide more energy to living beings.
