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.
Different structures are involved in gas exchange in other vertebrates. The alveolar membrane is the gas-exchange surface. Carbon dioxide rich blood is pumped from the rest of the body into the alveolar blood vessels where, through diffusion, it releases its carbon dioxide and absorbs oxygen.
