Change: •Surfactant is normally released into the lung tissues where it helps lower surface tension in the airways. This helps keep the lung alveoli open. When there is not enough surfactant, the alveoli collapse. As the alveoli collapse, damaged cells collect in the airways, creating a “hyaline membrane.”chest x-rays   View changes from previous version. (Word count: 877)
