At 13 inches, this lightweight teaching tool uses two flexible sacs as lungs, a rubber diaphragm to simulate muscle movement, and a clear plastic chest cavity to reveal air flow patterns. Its simple, durable design supports hands-on learning in classrooms, labs, and home study without complex equipment.\u003c\/p\u003e\n\u003ch2\u003eWhat you will observe\u003c\/h2\u003e\n\u003cp\u003eThe transparent enclosure lets students watch air move as the lungs inflate and deflate. By gently pulling the bottom rubber section, you can illustrate diaphragm contraction and relaxation, linking muscle action to changes in chest volume. This direct, visual approach complements a wide range of biology and physiology topics without overwhelming setup requirements.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo soft sacs mimic lung tissue and demonstrate fill\/empty cycles clearly.\u003c\/li\u003e\n  \u003cli\u003eA flexible rubber diaphragm shows how muscle movement relates to air flow.\u003c\/li\u003e\n  \u003cli\u003eThe clear housing reveals airflow dynamics within a simple chest cavity model.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to use\u003c\/h2\u003e\n\u003cp\u003eUse the model for instructor demonstrations or student-driven exploration.
