Aids And Adaptations What Adaptations Aid In Exchange Of Molecules In The Respiratory System?

What adaptations aid in exchange of molecules in the Respiratory System? - aids and adaptations

I suspect that "exchange of molecules" refers to oxygen and carbon dioxide between the blood circulates around the alveoli and air in the alveoli themselves. As these gases move only the process of disseminating their concentration gradients that allow adjustments to happen this distribution, be an advantage. Two to us spontaneously --

1. The cells which form the walls of the alveoi and cell walls of the capillaries that surround them, the very thin so the gases are not very widespread. This means that it is much faster.

2. The large number of cells, each individual is small, if you have a large area. The comparison that we teach to use in Class I, is the size of half a tennis court. Even for the largest surface area of gas exchange will be faster.

Also - although I'm not sure whether I, as an adaptation of respiratoy or not classified, but it is significant to the alveolar capillary beds andReturn to a relatively low blood pressure, and again there is plenty of space and time for the dissemination occurs.
