When at rest, humans exhale about 17.5 ml of water per hour, but they lose about four times that amount during exercise. The video shows learners how worms, insects, fish and humans all respire very differently. Viewers then explore the major organs of the respiratory system—the pharynx, trachea, bronchus, bronchiole, and alveoli  and their role in gas exchange. Video nine in a series of 21.
