Mechanism of diaphragmatic respiration

Principle

Mechanical model experiment for the demonstration of how the human lung work. The model shows the expansion of the lungs (rubber balloons) when the breast area (polystyrene jar) is expanded by sinking the diaphragm (rubber cloth). Air flows into the lungs through the windpipe and bronchi (Y-tube).

Benefits

• Graphic demonstration experiment
• Easy to demonstrate
• Easy to understand

Tasks

• Demonstration of diaphragmic respiration using a lung function model
