The 85cm male trunk model is a standardized simulation teaching aid often used in medical teaching and experimental training. It is designed to be 85cm in height and made in accordance with the anatomical proportions of an adult male trunk. It can clearly display the important organ structures of the thoracic cavity, abdominal cavity and some parts of the pelvic cavity. Models typically include major organs such as the heart, lungs, liver, stomach, small intestine, large intestine, and kidneys, and are presented in a layered or detachable form, making it convenient for learners to observe and operate one by one.

This model is mostly made of durable high-molecular resin or plastic materials, with vivid colors and clear markings on the surface of organs, enabling learners to intuitively identify the positions and relationships of different tissue structures. Some high-end versions also feature transparent components or cross-section designs, which help students understand the hierarchical relationship and spatial distribution of the internal structure. Through repeated disassembly and assembly, learners can enhance their mastery of human anatomy knowledge and establish a systematic sense of space.

In terms of application, the 85cm male trunk model is not only suitable for anatomy teaching in medical student classrooms, but also widely used in nursing, first aid training and health education promotion. It provides learners with a low-risk and intuitive operation platform, which is conducive to improving the mastery of clinical skills. In addition, this model is of moderate size and complete structure, which is not only convenient for classroom display but also suitable for long-term use in laboratories and training centers.

Therefore, the 85cm male trunk model is of great significance in medical education, skills training and popular science publicity, and serves as an important bridge connecting theory and practice.
