Explanation

The process of taking air into the lungs through nose and then expels it through nose is called as breathing. When we breathe in; the air moves from outside to the inside of our body. In addition, when we breathe out then the air moves from inside our body to the outside. Air contains oxygen gas so the purpose of breathing in air is to provide oxygen to our body for carrying out respiration. Thus, breathing is a part of the process of respiration.
