How are the alveoli designed tomaximise the exchange of gases?

Expert Answer:

The walls of alveoli contain an extensive network of blood vessels. The blood brings CO2 from the rest of the body for release into the alveoli and oxygen in the alveolar air is taken up by blood in the alveolar blood vessels to be transported to all the cells in the body. Thus due to the large network of blood vessels, maximum exchange of gases can take place in the alveoli of lungs.
