Material and design: The model is made from carefully selected PVC for light weight, solidity, and durability. It is not easy to break. Each trachea is rendered with a realistic image, the texture is clear and natural, and the internal anatomy of the hen is visible. Removable organs for handson learning: Internal organs are removable, making teaching and experiments more intuitive. Bolts provide a secure yet removable fit, allowing easy disassembly and reassembly to help learners understand the components of the animal. Stable and sturdy construction: The model sits on a base that is stable and firm, fixed by multiple screws. This design prevents tipping and supports clear study and reference during demonstrations. Detailed hen anatomy: The mold carefully depicts the hen's internal organs, including the esophagus, lungs, ovaries, kidneys, trachea, crop sac, heart, fallopian tube, liver, duodenum, and sand sac, providing intuitive visual detail for study. Use scenarios: Classroom biology or anatomy lessons: use for demonstrations and guided dissection practice to reinforce anatomical relationships. Veterinary technician or veterinary student training: handson exploration of organ placement and connections to support practical understanding. Selfstudy and laboratory reference: a durable, reusable model for individual learning and quick reference during research or exam preparation.
