Chapter - 5 Date Human Day Thurad lelearning obie Respiratory System which is one of the most important organ systems of tract continuously contract and relax, due to which the ingested food gets digested and provides nutrients to body. The fact is that the muscles of our digestive tract need oxygen to work properly. This oxygen comes from the process of respiration. So before studying about the human respira respiration is? RESPIRATION Respiration is the process of release of energy (ATP) by the breaking down of glucose (an organic substance) present in the digested food of the living body. All organisms including human beings obtain oxygen from the air. When the glucose present in digested food combines with oxygen, it completely breaks down and a large amount of energy is released with the liberation of carbon dioxide and some amounts of water vapours. In the absence of oxygen, the incomplete breakdown of glucose releases less amount of energy. In respiration, the energy released in the form of ATP (adenosine triphosphate) molecules. It is a chemical process. Glucose + Oxygen Carbon dioxide + Water + Energy (ATP) Phough, the process of respiration looks simple, but it PHASES OF RESPIRATION The process of respiration has two stages-breathing and cellular respiration. cellular respiration. Breathing or External Respiration It is a physical process which involves inhaling air rich in oxygen and exhaling air rich in carbon dioxide.
