Blackened beyond recognition by a constant barrage of tar, this 5" x 9" x 4" lung yields not a single hint that it was once a smooth, pink, efficiently functioning organ. Damaged beyond repair by cigarettes, this BIOLIKE 2™ model of a right lung shows severe damage from emphysema and features a cross-sectioned upper lobe that reveals a fibrous pale-white cancer. Great for smoking cessation and tobacco prevention programs.
