In [external/ or cellular] respiration, these gases are exchanged between the body's tissues and the outside environment by way of the respiratory system. In [ external/ or cellular] respiration, these gases are used and created by the metabolic processes of the cells.
[alveolar capillary membranes, type 2 alveolar cells, type 1 alveolar cells] make up the main structure of the alveolar wall. The walls of the alveoli are very thin, separated from the capillary vessels by an even thinner barrier called [alveolar capillary membranes, type 2 alveolar cells, type 1 alveolar cells] . [alveolar capillary membranes, type 2 alveolar cells, type 1 alveolar cells] occur on the inside surface of the alveoli and secrete liquids called pulmonary surfactants, to help the surface of the alveoli expand.
