The 85cm male trunk model (19 pieces) is a medical teaching tool with a clear structure and high disassemblability, suitable for basic anatomy, nursing education and clinical demonstration. The model is designed based on the body proportions of adult men, with a moderate height, which is convenient for classroom demonstrations and close observation by students. Its 19 detachable components cover the thoracic cavity, abdominal cavity and some pelvic organs, including common organs such as the lungs, heart, liver, stomach, kidneys and intestinal segments. The structural boundaries are clear and the organ layers are distinct, which can effectively support the explanation of system anatomy and the positional relationship of organs.

Teachers can demonstrate the front-back, up-down and adjacent relationships of organs through disassembly and assembly operations, which is helpful for students to establish a concept of three-dimensional anatomy. The model is simultaneously applicable to courses such as nursing, first aid, and rehabilitation, and is used to illustrate common diseases, operational risk points, or pathological change mechanisms. Its material is durable and the color is realistic, making it an ideal tool for classroom teaching, laboratory training and health science popularization display.
