There are numerous alveoli - air sacs, supplied with gases via a system of tubes ( trachea, splitting into two bronchi - one for each lung - and numerous bronchioles) connected to the outside by the mouth and nose. These alveoli provide a massive surface area through which gases can diffuse. sparkly wedding flip flops
