Alveolar type II cells secrete a lipoprotein material called surfactant, whose primary function is to reduce the surface tension in the alveoli.
What cells secrete surfactant?
The pulmonary surfactant is produced by the alveolar type-II (AT-II) cells of the lungs. It is essential for efficient exchange of gases and for maintaining the structural integrity of alveoli. Surfactant is a secretory product, composed of lipids and proteins.
What do type I and type II alveolar cells do?
The type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange surface in the alveolus. On the other hand, the type II cell acts as the “caretaker” of the alveolar compartment.
