The walls of the alveoli are composed of two types of cells, type i and type ii alveolar cells. the function of type ii alveolar cells is to the walls of the alveoli are composed of two types of cells, type i and type ii alveolar cells. the function of type ii alveolar cells is to

The answer would be: secrete surfactant

Type II alveolar cells will secrete surfactant that will reduce the surface tension of the alveoli. A high surface tension will cause the lungs hard to inflate when doing inspiration. Respiratory distress in premature baby mostly caused by surfactant deficiency as their lungs can't produce it.
