You'll hear about two alternative ways of liberating energy. One involves the presence of oxygen, and is called aerobic respiration. The other enables energy to be released without oxygen, and is called anaerobic respiration. Some micro-organisms that can respire anaerobically produce alcohol and carbon dioxide. Prolonged intense exercise in animals can result in a build-up of lactic acid in the muscles. This leads to a condition known as oxygen debt. This title also looks at the structure and functions of the respiratory system, including the structure of the lungs. We'll examine the mechanics of getting air into the lungs, so that oxygen in the air can get into our blood, and to the cells that need it.
