epithelial
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
Squamous epithelial lining of alveolus Endothelial cells lining an adjuacent capillary Fused basal laminae between alveolar and endothelial cells
chlorophyll molecules are located in the thylakoid membrane
plasma membrane
Alveolar squamous cells and Capillary endothelial cells.
cytoplasm
The respiratory membrane is formed by a combination of the walls of alveoli and walls of capillaries. It consists of type 1 alveolar cells, a basement membrane, capillary endothelium, alveolar epithelium and macrophages.

alveolar and capillary walls and their fused basement membranes
In cells that do not have cell walls, the cell membrane is located on the outer side of the cell, and is made of a phospholipid bilayer.
chlorophyll molecules are located in the thylakoid membrane
The Respiratory membrane: The wall of the alveoli are composed primarily of a single layer of squamous epithelial cells, called type I cells, surrounded by a flimsy basement membrane. See page 815 anatomy and physiology 8th
plasma membrane
Alveolar macrophages, aka DUST CELLS.
