ADA-307B: Reading a Heart Model From the Outside In

Short answer: ADA-307B is a new-style life-size heart model supplied in two parts. Externally it shows the ventricles, atria, valves, veins and the aorta in anatomical detail; the front heart wall is removable so the chambers and internal structures can be viewed directly. Two parts is the minimum configuration that supports seeing inside, and that is exactly what this model is built to do.

Key takeaways

• The removable front wall is the whole feature. Everything else is the standard anatomy; the ability to lift the front wall is what converts a display model into a teaching model.
• Published external detail: ventricles, atria, valves, veins and the aorta.
• Two parts, not nine. Fewer parts means less assembly time and fewer pieces to lose, which suits frequent handling.
• Life-size — the proportions students see on the model are the proportions they will meet in practice.
• Price is not published; the page routes enquiries to a quotation form.

Why the physical heart still earns its place in a digital curriculum

The strongest evidence for physical cardiac models comes from a direct randomised trial. A study compared three-dimensional printed models with cadaveric materials for learning external cardiac anatomy and found the physical models usable and effective for that purpose [1]. The point of that trial is not that printing replaces cadavers; it is that a physical object carries cardiac anatomy in a way students can handle and revisit.

The counter-case is worth stating honestly too. A 2026 study asked whether virtual reality or tablet-based mobile applications were better for enhancing heart anatomy education in middle schools [2] — digital tools are being tested seriously, and they have real advantages in cost and scale. But the same literature shows the trade-off is about access and repetition, not about spatial understanding. Where a student has to relate a valve to a chamber and then to the aorta in one continuous view, a life-size object with a removable wall remains the simpler instrument. The practical conclusion for a department is to buy the physical model for bench teaching and use digital resources for pre-class preparation and revision.

How to sequence a lesson with it

1. External landmarks first. With the front wall in place, identify the aorta, the veins and the division between atria and ventricles. The model is life-size, so the proportions being taught are real.
2. Lift the front wall. Reveal the chambers and internal structures. The lesson moves from what can be seen from outside to what cannot — the same sequence used for any dissection.
3. Follow one direction of flow. Trace a path from vein to atrium to ventricle to aorta, using the valves as checkpoints. Valves are the published feature that makes direction teachable.
4. Replace the wall and test. Ask a student to point to a named chamber or valve with the wall back in place. This is the step that separates recognition from recall.

Q6. How do I request the specification and a quotation?
Email cprmodel@adaanatomy.com with the model (ADA-307B) and the details you need — material, stand, dimensions, carton data or price.

Request a quotation

Write to cprmodel@adaanatomy.com for the ADA-307B specification sheet and a quotation. If the department also teaches CPR and airway skills, ask about the lung and airway models in the same enquiry so that the whole teaching set ships together and the carton data is calculated once.
