    Observe the respiratory system slides under the microscope. Remember to follow the microscopy procedure outlined in the microscopy lab! Use Figure \(\PageIndex{1}\) and Figure \(\PageIndex{2}\) as a guide for what you are looking for on the slides.

    Please focus the slides to 100x total magnification and take the images of the slides at 100x.

    • Lung tissue slide, label the following structures on this slide:
      1. Respiratory bronchiole
      2. Alveoli
    • Trachea, label the following structures on this slide:
      1. Mucosa (the mucosa layer contains the pseudostratified ciliated columnar epithelium)
      2. Submucosa (look for what looks like open glands to identify the submucosa layer. It will be in between the hyaline cartilage layer and the pseudostratified layer)
      3. Hyaline cartilage

    Microscopic image of lung tissue highlighting alveoli, blood vessels, and bronchiole structures, labeled for reference.
