the squamous alveolar epithelium

|
|
the endothelial cells lining an adjacent capillary

|
|
the fused basement membranes that lie between the alveolar and endothelial cells

all of the above

Detailed explanation-1: -The respiratory membrane, also called the respiratory surface, is made of the alveolar epithelial cell and the pulmonary capillary endothelial cell, and this structure helps exchange the gases carbon dioxide and oxygen.
Detailed explanation-2: -The respiratory membrane consists of the alveolar and capillary walls. Gas exchange occurs across this membrane. Characteristics of this membrane follow: Type I cells are thin, squamous epithelial cells that constitute the primary cell type of the alveolar wall.
Detailed explanation-3: -The four layers of the respiratory membrane are: The alveolar wall which is made up of type I and type II alveolar cells. The epithelial basement membrane that is found under the alveolar wall and is composed of epithelial cells.
Detailed explanation-4: -Answer and Explanation: c. A thin layer of ciliated epithelial cells is not part of the respiratory membrane.
Detailed explanation-5: -Alveolar wall. Basement membrane. Capillary wall. 31-Dec-2021
