Human Torso, 14 parts, Sexless

Quick Answer: The human torso, 14 parts, sexless, is a head-and-trunk anatomy model with removable internal organs and no genital or reproductive parts. A sexless torso model keeps the lesson on the respiratory, circulatory, digestive and urinary organs and is widely chosen for school classrooms.

Why a Sexless Torso

Sexless, sometimes written as asexual or unisex, means the torso is modelled without external genitals or internal reproductive organs. Many schools choose this deliberately. It keeps younger classes focused on the organs of breathing, circulation and digestion, and it avoids managing reproductive inserts, which can be taught with separate models when the syllabus reaches them.

The 14 parts are the torso body and its removable pieces. In a torso of this kind the head is often split to show half of the brain, and the thoracic and abdominal organs, lungs, heart, stomach, liver and intestines, come out in turn. Which organs are separated, and whether any muscles are shown, is not detailed in the title and is a matter for the parts list.

Teachers who need both sexes can compare the 13 part male and female torso. A sexless torso also pairs well with the human digestive system model when digestion is taught in more depth.

Specifications

Applications

• Lower and middle secondary biology lessons on body systems
• Health education where a neutral model is preferred
• Identifying organs and their positions in practical tests
• Explaining how the diaphragm separates the thorax from the abdomen

Care & Handling

• Lay the removed organs of the sexless torso model on a soft cloth so they do not roll off the bench.
• Check the head halves and organ pegs for cracks at the end of each term.
• Store the model assembled and covered in a cupboard.

Why Choose LabEquip

Schools that teach body systems before reproduction often standardise on a sexless torso. LabEquip includes this one in its biology lab products; ask through the LabEquip contact page for the parts list.

Frequently Asked Questions

What does sexless mean for a torso model?

It means the model has no reproductive organs or external genitals. The torso shows the other organ systems only, which makes it neutral for use with younger classes.

Can reproductive anatomy be taught with this torso?

Not directly. Schools using a sexless torso usually teach reproduction with charts or separate reproductive organ models when the topic comes up in the syllabus.

Which organ systems can be taught with it?

The respiratory system with the lungs and trachea, the circulatory system with the heart and main vessels, the digestive organs and usually the kidneys of the urinary system, depending on the model.

What separates the thorax from the abdomen?

The diaphragm, a dome-shaped sheet of muscle. The heart and lungs lie above it, and the liver, stomach and intestines lie below it.

Is 14 parts enough for secondary school?

Yes for most lower and middle secondary work, which focuses on the positions and functions of the main organs. Senior classes may add organ models such as a heart or kidney for internal detail.

How should the model be cleaned?

Wipe the torso and organs with a soft cloth lightly dampened with water and mild detergent, then dry them. Avoid alcohol and solvents, which can remove the paint that distinguishes the organs.
