the alveoli provide a suface where exchange of gases can take place. The walls of the alveoli contain an extensive network of blood vessels.when we breath in, we lift our ribs and flatten our diaphragm,and the chest cavity becomes larger as a result. Because of this,air is sucked into lungs and fills the expanded alveoli.
Wherever capillaries are found, these are places where nutrients and wastes are exchanged.
