76. alveolar sac. A cluster of alveoli located at the end of each alveolar duct in the lungs; each of the alveoli is a tiny, thin-walled, capillary-rich sac, lined by a simple squamous epithelium, where the exchange (diffusion) of oxygen and carbon dioxide (and other less important gases) takes place.he squamous epithelial cell forming the alveolar wall and through whose cell membranes and cytoplasm the exchange of oxygen and carbon dioxide (and other less important gases) takes place; collectively they cover 95% of the alveolar surface area.
