Yes it is. Infact, the alveolus is made up of a single layer of epithelial tissue.
In the alveoli
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.
The alveoli is just one cell layer thick so that diffusion of gasses between the capillaries and the alveoli is easy. Simple squamous epithelium are found in the capillary walls and the alveolar walls. They are thin so diffusion is easy.
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
This tissue is simple squamous, a type of epithelium. It is the thinnest tissue, one cell thick, since gases are exchanged in the aleoli and capillaries surrounding them.
These are called the alveoli capillaries.
as it moves through blood vessels capillaries in the alveoli walls, your blood takes oxygen from the alveoli and gives off carbon dioxide to the alveoli
The structure in the lungs that contains the thinnest epithelium is the alveoli. Alveoli are air sacs where the exchange of gases takes place.
Respiratory bronchioles, alveolar ducts, and alveoli.
The alveoli are surrounded by capillaries that carry carbon dioxide laden blood from the body and return oxygenated blood back to the body.
Yes, capillaries form a network around the alveoli. It is through the alveolar walls and into the capillaries that oxygen enters the blood stream. Carbon dioxide leaves the blood by the reverse route.
the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.
