Respiratory system design limitations study guide 1. Understand the two types of lung design; the one mammals have and the limitations to this design. Design 1: the ventilation pump is separated from the gas exchanger. In the first method you could design the ventilation system that would suck air in from the atmosphere and the gas exchange structure where diffusion of oxygen and carbon dioxide occurs as separate entities. In this situation you would need a holding tank for the air that is sucked in and then you would need some method of “blowing” the air in the holding tank over a specially designed gas exchanger. This design is very appealing because you could optimize the two systems – make the ventilation system really strong so it could stand up to the constant and repeated forces of sucking air into the holding tank and then blowing the “stale” air out. This is resembles the birds respiratory system. Design 2: The gas exchanger is placed in the ventilation pump that is alternately inflated and deflated drawing air through the gas exchanger and then back out. An engineer would probably object to this design because it would be prone to problems, in part because the delicate gas exchanger with very thin walls may be damaged by the repeated movement of sucking air in and then blowing it out. Yet, this is the arrangement that has
