Respiration is the process of physiological gas exchange, which occurs in the cells of all living organisms to produce energy from food molecules It involves the exchange of O2 (oxygen) and CO2 (carbon dioxide) between the internal environment of the organism and the external environment. The main organ responsible for respiration is the lungs, but other organs such as the skin, the cerebrum, and the gastrointestinal tract also play a role. During respiration, oxygen enters the body and is used to break down sugar molecules in a process called aerobic respiration. The energy produced through respiration is used for all the metabolic processes of the body.
