The 42cm male trunk model (13 pieces) is a standardized human anatomy demonstration model specially designed for basic medical teaching.

This model is scaled down in proportion to the body shape of an adult male and made of environmentally friendly PVC material. It features a fine structure and vivid colors, and can clearly display the spatial layout of the human chest cavity, abdominal cavity and some pelvic organs.

The model can be disassembled into 13 components, including the head, trunk shell, lungs, heart, stomach, liver, pancreas, kidneys, intestines and other major organs, which is convenient for disassembly and assembly as well as independent observation. Through this model, learners can intuitively understand the positional relationships, morphological characteristics and interconnections of the main internal organs in the human body.

This model is widely used in medical colleges and universities, biological laboratories and clinical teaching demonstrations. It has the advantages of simple operation, clear hierarchy and strong teaching practicality, and is an important auxiliary tool for human anatomy teaching.
