{"product_id":"lung-apparatus-basic","title":"Lung Apparatus, Basic Demonstration Model","description":"This basic lung apparatus is designed to demonstrate diaphragm function, lung expansion, and air movement during breathing. The model uses lung-shaped balloons inside a clear plastic housing to show how changes in pressure and volume affect airflow in a simplified respiratory system.\u003cbr\u003e\u003cbr\u003eThe apparatus provides a visual way to connect biology and physical science concepts. As the diaphragm model moves, students can observe how the lungs inflate and deflate, helping illustrate the relationship between air pressure, volume change, and respiration mechanics.","brand":"GSC International","offers":[{"title":"Default Title","offer_id":49507441541397,"sku":"GSC120320","price":34.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/120320.jpg?v=1761837718","url":"https:\/\/unitedsupplycorp.com\/products\/lung-apparatus-basic","provider":"United Supply Corp.","version":"1.0","type":"link"}
