This item is composed of 3 different models on the same base: the first one reproduces a 3X life-size cross-section of the human trachea; it can be longitudinally divided into two parts to show the inner anatomy.

The third one shows the magnified pseudo-stratified ciliated epithelium in great detail: it displays the typical ciliated cells and mucous cells
