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.
1 Describe the changes in the type of epithelium throughout the respiratory system. 2  Explain how the structure of different segments of the respiratory airways reflect the functional roles that these airways play in air movement and gas exchange.espiratory bronchioles also have cuboidal epithelia, but contain some alveoli. Alveolar Sac and Alveolus: An alveolar sac contains many alveoli. Type I and Type II Pneumocyte: Type I pneumocytes are squamous cells that support gas exchange; type II pneumocytes are cuboidal and create pulmonary surfactant.
