BP-39 RESPIRATORY SYSTEM WITH BOX & BALLOONS / BIOLOGY PROJECT & MODEL

This simple Bell jar model lung can be used to demonstrate the basic principles of breathing. The model should be assembled as in the diagram
Working parts of the model are pre-fabricated on the base in the duly working state, but the decorative model parts/pieces in the box are in the loose form and are to be pasted by the student themselves. This is to ensure safe delivery of the parcel.
