The alveoli are open to the environment so alveolar pressure (i.e. the pressure inside the lungs) is really the same as atmospheric pressure. Intrapleural pressure is the pressure of the air in the pleural cavity in which the lung sits (the space between the lung tissue and the chest wall).
An alveolus is a tiny air sac formed at the tip of the lungs' smallest airways, the bronchioles. The primary function of the alveoli is the exchange of carbon dioxide for oxygen.Tissues within the alveoli also carry out secondary functions, such as the production of hormones, enzymes, and pulmonary surfactant.he exchange of carbon dioxide for oxygen is the primary function of the alveoli. The capillaries of the alveolus branch from both the pulmonary artery and the pulmonary vein.
