The alveoli have a high surface tension due to a liquid film that covers their walls, making it difficult to inflate them. Additionally, the presence of surfactant helps to reduce surface tension in the alveoli, making inflation easier. When the alveoli are collapsed or have decreased compliance, it can also make it challenging to inflate them.
