Oxygen is required for catabolic processes and carbon dioxide is released in the process. * Carbon dioxide which is harmful is also released during the above catabolic reactions. Solution: Vital capacity is defined as the maximum volume of air a person can breathe in after a forced expiration or the maximum volume of air a person can breathe out after a forced inspiration.
