During the development of this work, potassium hydroxide and formalin were replaced, in the injection-corrosion method used to obtain anatomical models, by other elements of daily use, such as papaya, pineapple, and coca-cola®, which involve less environmental pollution and low risks for the staff in charge of handling these reagents. In the process of parts production of the respiratory system, we used lungs of canines that died from natural causes or diseases that did not affect the respiratory system, we performed the dissection in order to obtain the complete bronchial tree, we proceeded to weigh them, then we cannulated veins, arteries, trachea, the structure was filled with resin, dyed with acrylic paint, a mixture of papaya, pineapple, and coca-cola® was used as corrosive elements for the elimination of tissue. Parameters such as the initial weight, final weight, and loss of organic material (tissue), morphological changes that happened throughout the process were evaluated. In addition, fortuitous changes in the solution were reported, as in the case of lungs immersed in coca-cola®, in which fungi have grown; on the other hand, it has been observed that the resin is more efficient for repletion. It was determined that the lungs dipped in pure coca-cola® lost more organic material. The mixture of fruits and coca-cola® generates tissue detachment in large portions, and there is no significant damage to the mold, the architecture is preserved, so it is considered that it would be very useful to replace potassium hydroxide. Moreover, the resin has a higher level of resistance than silicone, by being immersed in corrosive substances and does not lose its consistency.
