What is the importance of respiration?

Respiration is important because it produces energy that is necessary for the functioning of the body. It provides oxygen to the cells and expels toxic carbon dioxide. When oxygen reaches the cells, this oxygen breakdown glucose which is present in digested food, and releases energy.
