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.
type II alveolar cells
The lower epidermis has three main types of cells. These three main types of cells are the guard, subsidiary, and pavement cells.

secrete surfactant
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.
type II alveolar cells
Alveolar macrophages, aka DUST CELLS.
alveolar fluid
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
type 1 alveolar cells
Alveolar squamous cells and Capillary endothelial cells.
The lower epidermis has three main types of cells. These three main types of cells are the guard, subsidiary, and pavement cells.

false, there only two types of electrochemical cells. Wet and dry cells.
