In the alveoli
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
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.
Alveolar connective tissue is a type of loose connective tissue found in the alveoli of the lungs. It provides support and structure to the alveoli, which are responsible for gas exchange in the lungs. Additionally, alveolar connective tissue contains capillaries that facilitate the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.
the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.
The humorus
Capillaries - Apex Cheater /Thugs
These are called the alveoli capillaries.
The smallest blood vessels of the body = capillaries
Oxygen passes into the capillaries that surround the alveoli. The thin walls of the capillaries make this diffusion easier.
Alveoli.
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
