With the aid of this set of powerpoint slides you will revise the following concepts:
- structure of the respiratory system, its labelling
- alveolus and its structure
- gaseous exchanges at the alveolar surface
- scanning electron micrograph of the cilia cells, the goblet cells of the trachea and bronchi
