THE STRUCTURE OF THE PULMONARY ALVEOLI AND THEIR ROLE IN GAS EXCHANGE
Abstract
The alveoli of the lungs are the main functional structures of the respiratory system. They play a central role in gas exchange, i.e. the transfer of oxygen into the blood and the removal of carbon dioxide from the blood. This scientific article provides an in-depth analysis of the microscopic and histological structure of the alveoli, their cellular composition, the role of cells in surfactant production, the morphology of the alveolar wall, and their relationship with capillaries.
