Oxygen and Carbon Dioxide Transport in the Blood

WebAn alveolar sac consists of two or more alveoli that share a common opening to alveolar duct . On the outer surface of each alveolar sac, a network of pulmonary capillaries is found . b. Alveolar walls consist oftype I alveolar(simple squamous epithelial) cells, type II alveolar(septal)cells, and alveolar macrophages (dust cells). c. WebThe alveoli are surrounded by tiny blood vessels, called capillaries. The alveoli and capillaries both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.

WebPulmonary diffusion is further aided by a thin respiratory membrane composed of the membrane of the alveolar cells and the cells making up the wall of the capillary. So, the respiratory membrane through which gases must pass to move between the blood and the air within the alveoli is only two cells thick. http://lsa.colorado.edu/essence/texts/lungs.html
