Tarred Lung Model
Watching as simulated tar coats the inside of an air sac like dirty petroleum, viewers will understand the toll smoking takes on smokers’ health as their lungs fill with thick, choking tar instead of clean air. Cut in cross section, this lung features a greatly magnified model of an alveolus that shows how poisonous tar creeps into even the tiniest structures of the lung. Artwork depicts damage from emphysema. Comes with an informative, two-sided tent card. Model measures 18 cm x 28 cm.
