This 5-minute video shows a teacher from Preston College (UK) inflating sheep lungs. There is also a brief view of a fully dissected set of lungs that shows the trachea, bronchioles, and individual lobes. This could be shown to a class or used as an instructional guide for a teacher.
Blowing via a piece of rubber tubing into the lungs with your mouth is not a recommended procedure due to the possibility of inhaling aerosols from the lungs as the air is expelled. It is best practice to use a bicycle pump. In addition, it is good practice to wear safety glasses during all dissections.
Questions to ask students;
Why do the lungs appear a pink/red colour?
What is the major tube that leads to the lungs called?
This tube splits into two smaller tubes. What are these called?
In which part of the lungs does the gas exchange occur?
