"WebThe alveoli are a part of the respiratory system that exchange gas and blood. The alveoli's elastic fibers allow for them to expand with air (when you breath in) and contract when you breath out. The alveoli are only found in mammals, while other structures are used for gas exchange in other vertebrates. The alveoli has the form of a hollow cavity. " - Elastic fibers in alveoli
