Quick Answer: The human torso, 13 parts, male and female, is a head-and-trunk model whose organs separate into 13 pieces and which can represent either sex, usually through swappable reproductive parts. As a 13 part torso model it is a straightforward choice for secondary schools and first-year nursing courses.
A Simpler Two-Sex Torso
With 13 parts, this torso sits at the simpler end of the range. Fewer pieces means the organs come out as larger blocks, such as a lung, the heart, the stomach, the liver and the intestines, and a student can reassemble it in a few minutes. For classes meeting organ positions for the first time, that simplicity is an advantage rather than a drawback.
Male and female in the title indicates that the model can show either sex. Torsos described this way usually have interchangeable genital parts, sometimes with swappable chest pieces as well, but the listing does not say how this model does it, and that is worth confirming along with the parts list.
Schools that need finer detail can compare the 24 part torso with interchangeable sex organs; for classes that should not handle reproductive parts, the 14 part sexless torso is the alternative.
Applications
- First lessons on organ positions in secondary biology
- Introductory reproduction lessons comparing male and female anatomy
- Nursing foundation courses and health worker training
- Practical stations where students name organs as they remove them
Specifications

| Parts | 13, as listed |
| Sexes represented | Male and female, as listed |
| Organ systems covered | Main thoracic and abdominal organs |

Care & Handling
- Count the 13 parts of the torso at the end of each lesson; with so few pieces, a missing one is noticed at once.
- Store the model upright on its base with the organs in place so they keep their fit.
- Clean with a soft cloth dampened with water and a little mild detergent.

Frequently Asked Questions
What does male and female mean for this torso?
It means the model can show either male or female anatomy, which on torsos of this type is normally done with interchangeable reproductive parts. It saves buying two separate torsos.
Is a 13 part torso detailed enough for nursing students?
For foundation anatomy, yes: it shows the positions and shapes of the major organs. For advanced study of heart chambers or kidney structure, separate organ models add detail.
Which organs are usually removable?
Typically the lungs, heart, stomach, liver and intestines, with reproductive parts for each sex. Some 13 part models also include half of the head with the brain.
How is it different from the mini torso?
The mini torso is a small desk model for young students. A 13 part torso is usually larger, with bigger organs for class demonstration, although the height of this one is not given in the title.
Where does the liver sit in the torso?
Mostly in the upper right abdomen, under the right dome of the diaphragm and partly protected by the lower ribs. The gall bladder lies under its lower edge.
Why do some schools prefer fewer parts?
Fewer parts are faster to take apart and reassemble, are less likely to go missing, and keep the lesson focused on where the main organs sit rather than on fine detail.
