☆ Respiration ☆

All the living things need energy to grow ,move and stay alive. They get this energy from food through respiration, Respiration is the chemical process in which food taken by an organism combines with oxygen to release energy. This energy is used by the organism to carry out its various life processes. Carbon dioxide and water are the other products of the process of respiration.

All the living things undergo respiration to obtain energy from food. For example, our body takes in oxygen from the air for respiration. At the same time it gives out carbon dioxide produced in respiration. This interchange of gases take place in our lungs. The process of taking air into the lungs through the nose and then expel it again through the nose is called breathing. The purpose of breathing in air is to provide oxygen to our body for carrying out respiration.
