Progress Monitoring Measures. â¢designed to assess the same core features as the. research and annual self-assessment measures. â¢used by school teams (typically with the support of. their coach) on a frequent basis (e.g. monthly, every. two months, or quarterly) to guide action planning. during the implementation process.
The basic function of alveoli is exchange of gases. Its structure is the site where the gaseous exchange during respiration takes place. These structures are surrounded by capillaries carrying blood. The exchange of carbon dioxide in the blood from these capillaries occurs through the walls of alveolus.
And some significant secretory function is retained, in the form of cuboidal, surfactant-producing great alveolar cells. Both in large glands and in the respiratory system, a system of conducting passageways form a branching tree, with functional units at the end of each twig.
