Question

Describe the importance of elastic fibres and lung surfactant in the function of alveoli.

Accepted Answer

Elastic fibres:Allow alveoli to stretch when air is drawn in, when they return to their resting size they help squeeze air out - elastic recoil of lungsLung surfactant:Thin solution layer the inner surface is covered with that makes it possible for alveoli to remain inflated at the end of exhalation
