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).
Around 700 million alveoli are present in a pair of lungs. Wrapped in capillaries, these alveoli have a surface area of around 70 square meters. While each alveolus is about 200 micrometers in diameter, its size can increase when a person inhales. These alveoli usually contain elastic fibers, along with collagen.There is a purpose of alveoli containing these elastic fibers. When alveoli need to be stretched, it is these elastic fibers that support stretching. When a person inhales, elastic fibers are filled with air.rapped in capillaries, these alveoli have a surface area of around 70 square meters.
