There are three major alveolar cell types in the alveolar wall (pneumocytes):
* Type I cells that form the structure of an alveolar wall
* Type II cells that secrete surfactant to lower the surface tension of water and allows the membrane to separate thereby increasing the capability to exchange gases.
* Type III cells that destroy foreign material, such as bacteria.
Surfactant is produced by the type II alveolar cells in the lungs. These cells secrete surfactant which helps lower surface tension in the alveoli, preventing collapse and facilitating gas exchange.
The cleanup cells, also known as alveolar macrophages, are located in the alveolar space within the alveolar membrane. They play a crucial role in clearing debris, bacteria, and other particles from the lungs to maintain respiratory health.

There are several types of white blood cells (leukocytes.) The 3 main groups are granulocytes, monocytes, and lymphocytes. There are 3 types of granulocytes; neutrophils, eosinophils, and basophils. There are 2 main types of lymphocytes; B cells and T cells. There are 4 types of T cells; cytotoxic T cells, helper T cells, suppressor T cells, and natural killer cells.

The alveoli, which are tiny air sacs in the lungs, are lined with a thin layer of epithelial cells called alveolar epithelium. This lining consists primarily of two types of cells: type I alveolar cells, which facilitate gas exchange, and type II alveolar cells, which produce surfactant to reduce surface tension and prevent alveolar collapse. The alveolar walls also contain a network of capillaries that enable the exchange of oxygen and carbon dioxide between the air and blood.
Surfactant is produced by the type II alveolar cells in the lungs. These cells secrete surfactant which helps lower surface tension in the alveoli, preventing collapse and facilitating gas exchange.
The most numerous cells in the lungs are the alveolar epithelial cells, specifically the type I alveolar cells which make up about 95% of the alveolar surface area. These cells are responsible for gas exchange and maintaining the structural integrity of the alveoli.
