What are the three types of alveolar cells?
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.
What are the Layers of the respiratory membrane?
The layers of the respiratory membrane include the alveolar epithelium, the basement membrane, and the capillary endothelium. These layers are involved in facilitating the exchange of gases, such as oxygen and carbon dioxide, between the air in the lungs and the blood in the capillaries.
What produces surfactant?
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.
In which membrane is the electron transport chain located?
The outer membrane is where the electron transport chain is located.
Where are the proteins of electron transport chains located?
The proteins of electron transport chains are located in the inner mitochondrial membrane in eukaryotic cells and in the plasma membrane in prokaryotic cells. They play a critical role in generating ATP through the process of oxidative phosphorylation.
The respiratory membrane consists of what cells?
Alveolar squamous cells and Capillary endothelial cells.
Where the cleanup cells are located?
cytoplasm
What is the structure of respiratory membrane?
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.

What are the most numerous cells in the lungs?
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.
Where is the electron transport chain is located?
The electron transport chain is located in the inner mitochondrial membrane of eukaryotic cells. In prokaryotic cells, it is located in the plasma membrane.
The respiratory membrane is a combination of?
alveolar and capillary walls and their fused basement membranes
Where are cell membrane located in cells that do have cell walls?
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.
What is alveolar macrophages also known as?
Alveolar macrophages, aka DUST CELLS.
In which membrane is the electron transport chain located?
The outer membrane is where the electron transport chain is located.
