Pneumocytes (pneumonocyte or alveolar cells) are one of the cells lining the alveoli (or air sac) of lung. Two types of pneumocytes exist: Type I and type II pneumocyte.

  • Type I pneumocytes makes up about 90-95% and are involved in the gas exchange between the alveoli and blood.
  • Type II pneumocytes function is to secrete surfactant, which decreases surface tension within the alveoli.
