Human Model Torso, Full size, 9 Parts

Quick Answer: The human model torso, full size, 9 parts is a life-size model of the human trunk with nine removable pieces, so the main organs of the chest and abdomen can be lifted out and studied. The full size torso model is used in secondary biology and introductory nursing to teach where organs lie.

Why Life Size Matters

A torso built at full size shows the organs at the size students will meet in their own bodies and, for nursing and first aid courses, in patients. That makes it easier to relate the model to surface landmarks: the heart behind the lower breastbone, the liver under the right ribs, the stomach under the left, the bladder low behind the pubic bone. Placing a hand on one’s own chest or abdomen while pointing to the same organ on the torso is a simple and effective exercise.

Nine parts is a moderate division. It is enough to lift out the main organs in a logical order, typically the lungs, heart, liver, stomach and intestines, together with front chest or head sections depending on the design, but the exact nine pieces should be confirmed at enquiry. Fewer parts also means faster assembly between classes and less risk of small pieces going missing, which matters in busy school labs.

Students can use the torso to see the diaphragm as the dividing line between the thoracic and abdominal cavities, to note how much space the lungs take up, and to see how the intestines are packed within the abdomen. Courses that also need both reproductive systems or a view from behind may prefer the 24 part dual-sex torso.

Specifications

Care & Handling

• Lift the full size torso model by its base with two hands; a life-size torso is heavy and awkward to carry by the shoulders.
• Store it under a cover on a low, stable shelf or trolley.
• Wipe organs with a soft, lightly damp cloth and dry them before replacing.

Applications

• Introducing the organ systems in secondary biology
• Relating organ positions to surface landmarks in first aid and nursing courses
• Showing the diaphragm as the boundary between chest and abdomen
• Quick identification quizzes in which organs are removed and named

Why Choose LabEquip

Schools and nursing colleges setting up an anatomy corner often start with a life-size torso with a manageable number of parts. LabEquip lists it with the rest of its biology lab products; send your requirements through the LabEquip contact page.

Frequently Asked Questions

What does full size mean for this torso?

It means the torso is made at about the size of an adult human trunk, so organs appear at their natural scale rather than reduced.

Which organs can be removed?

Nine-part torsos typically allow the lungs, heart, liver, stomach and intestines to be removed, with the remaining parts depending on the design. Confirm the exact list at enquiry.

Is a 9 part torso suitable for schools?

Yes. It shows the main organs without the many small pieces of more detailed torsos, which makes it quicker to assemble and easier to manage in a busy school lab.

Where is the diaphragm on the torso?

On most torsos it appears as the partition between chest and abdomen, arching up beneath the lungs and heart, with the liver and stomach tucked under its two domes.

How should students use the torso with their own bodies?

Ask them to place a hand where an organ lies on their own chest or abdomen while pointing to it on the model. This links the model to real surface landmarks.

How does it compare with the 24 part torso?

The 24 part model separates into many more pieces and adds interchangeable genital sections and an open back. The 9 part model is simpler and faster to use for general organ teaching.
