Product Details
This educational model cast from real specimens graphically illustrates the effects of smoking on the lungs. The first example shows the way normal lung tissue looks in a nonsmoker’s body. Contours of the normal lung are smooth and regular, and the color is healthy. The second piece depicts the way tissue from an emphysematous lung appears. It has a soft, irregular shape, a spongy texture, and blackened color. Collapsing air sacs within the lung will eventually smother the smoker. The third example is of cancer of the lung. The cancer appears as a large, whitish-gray mass. Use this display to teach the dangers of smoking in a way viewers will never forget. 9" x 12".
