A full introduction often acknowledges the ethical dimension. Mention that the specimen was humanely euthanized (usually via CO₂ inhalation) and preserved in a non-toxic solution (or formalin, with safety precautions). This demonstrates maturity and scientific responsibility. Providing the taxonomic background of the specimen is
A key focus of this experiment was comparative anatomy—the study of similarities and differences between species. It was hypothesized that the internal anatomy of the rat would closely mirror that of the human body in structure and function. For example, both organisms possess a four-chambered heart and a diaphragm, which aids in pulmonary ventilation. However, structural differences were expected in areas such as the digestive tract, specifically regarding the caecum and the absence of a gallbladder in rats, reflecting their herbivorous or omnivorous dietary adaptations compared to humans. Mention that the specimen was humanely euthanized (usually
