Last reviewed 01/2018
The alveolar-capillary complex is the site at which the pulmonary capillaries of the pulmonary circulation come into an extremely close relationship with the epithelial membranes of the alveolar sacs. Functionally, it is the site of gaseous exchange.
Histologically, it can be divided into two sections:
- thin walled
- thick walled
