how are alveoli designed to maximize the exchange of gases

they are
thin, moist membrane (allows gas diffusion) and large surface area (maximizes rates of diffusion).
1. large surface area. There are many alveoli and the shape allows for a high surface area. This is significant because it allows gas exchange to occur simultaneously over a large area.
2. high concentration of red blood cells. This allows for easy transport of oxygen and carbon dioxide since all the cells are simultaneously carrying these gases.

alveoli have thin walls and a close network of blood arteries to allow gas exchange between blood and air filled alveoli. they have a balloon like structure to maximize surface area in exchange of gases
