2-part heart model BIX-A1068 — life-size, separable at the atria, 15 x 8 x 9 cm on a stand, US$15.62. Built for individual handling.
...
Short answer: BIX-A1068 is a natural-size heart model in two parts, mounted on a plastic base, measuring 15 x 8 x 9 cm and listed at US$15.62 on the cprmodel page. Two parts means the model separates to show internal structure, but it does not disassemble into chambers, valves and vessels the way a 4X multi-part model does. The right choice depends on whether students must handle the model individually or see it from the back of a lecture theatre.
Key takeaways
| Criterion | BIX-A1068 (2-part, natural size) | 4X multi-part model |
|---|---|---|
| Size | 15 x 8 x 9 cm — close to life size | Four times life size; typically 30 cm or more |
| Parts | 2, on a plastic base | Typically 3–5 parts, sometimes with removable vessels |
| Internal access | Opens to show chambers; valves not removable | Chambers, valves and septa can be taken apart |
| Visibility in a lecture | Poor beyond the first row | Good from the back of a room |
| Student handling | Excellent — one per group is affordable | Usually one per department |
| Published price | US$15.62 | Not published on this page |
| Best use | Revision, self-testing, small-group tutorials, patient education | Lectures, demonstration, valve and septal anatomy |
| Learning objective | Achievable on BIX-A1068? | Note |
|---|---|---|
| Name the four chambers and great vessels | Yes | Exterior and opened view both show the arrangement |
| Trace blood flow through the heart | Yes | Works well as a hand-held walk-through |
| Identify valve leaflets and their attachments | Partly | Valves are visible but not removable |
| Compare normal with pathological anatomy | No | A normal model cannot show disease |
| Correlate with a chest CT or echo image | Yes | Life size makes the size comparison honest |
| Demonstrate to 60 students at once | No | Use a 4X model or projection for that session |
The evidence on physical models is more favourable than the technology narrative suggests. A meta-analysis of comparative studies on physical models in anatomy teaching found that physical models produced better learning outcomes than lectures alone or digital-only alternatives for spatial understanding [1]. A review of cardiac anatomy teaching made a related point: the terminology of "real" cardiac anatomy is itself contested, and students need a concrete reference object to reconcile textbook diagrams with dissection and imaging [2].
The counter-argument comes from the simulation literature: fidelity only helps when it serves the learning objective [3]. Applied to heart models, this means a department should not buy five 4X models for a tutorial room, and should not buy twenty 2-part models for a 200-seat lecture. The defensible split is one enlarged demonstration model plus a class set of natural-size models — which is exactly the budget arithmetic that US$15.62 makes possible.

Q1. What is BIX-A1068?
A natural-size heart anatomy model in two parts, mounted on a plastic base, measuring 15 x 8 x 9 cm.
Q2. How much does it cost?
The cprmodel page lists US$15.62. Confirm the price at your quantity before ordering, since carton data is not published.
Q3. Can the valves be removed?
The page describes two parts. Valves are visible when the model is opened but are not listed as removable components.
Q4. Is it suitable for a lecture hall?
Not for large rooms — at life size it is too small to be seen from the back. Use it for small groups and self-study.
Q5. Does it come with a stand?
Yes, the page states the model sits on a plastic base.
Q6. How do I order?
Email cprmodel@adaanatomy.com with the model number, quantity and delivery city, and ask for the carton quantity and gross weight.
Write to cprmodel@adaanatomy.com for the BIX-A1068 price at class-set quantity, the carton configuration and the delivery cost. If you need a demonstration model as well, ask for both in one quotation so the freight can be combined.
