Lung leaflet alveolar model BIX-A1069 — enlarged 28 x 21 x 14.5 cm view of terminal and respiratory bronchioles and alveolar epithelium, 25 parts.
...Short answer: BIX-A1069 is an enlarged teaching model of a lung leaflet that shows the structure of terminal bronchioles, respiratory bronchioles and alveolar epithelium. It is built with 25 indicating parts and measures 28 x 21 x 14.5 cm. Its job is not to show where the lungs sit in a body — it shows what the gas-exchange surface itself is made of, at a scale where a student can point at it.

To plan a sequence properly, write to cprmodel@adaanatomy.com quoting model BIX-A1069 and ask for the list of the 25 indicating parts and the package dimensions, so the labelling convention can be matched to the whole-lung models on the same bench.
| Stage of the sequence | What the student must learn | Model type that fits |
|---|---|---|
| 1. Position | Where the lungs sit in the thorax and how they relate to the heart and diaphragm | A torso or whole-lung model |
| 2. Gross branching | Lobes, segments and the main airway tree | A segmented or transparent lung model |
| 3. Functional unit (this model) | How the airway terminates and what the gas-exchange surface looks like | An enlarged leaflet model such as BIX-A1069 |
| 4. Histology | Cellular structure of the alveolar wall | Microscope slides and prepared sections |
The practical argument for stage 3 as a physical model rather than a diagram is size and scale. The alveoli are the part of the respiratory system that students consistently find hardest to picture, because the relevant structures are microscopic and their relationships are three-dimensional. An enlarged leaflet turns a micrograph into an object.
The case for physical anatomy models is well supported: a meta-analysis of comparative studies found physical models effective in teaching anatomy [1], and the systematic review of advances in anatomy education treats physical models as complementary to virtual and printed resources rather than as superseded by them [2].
For airway and respiratory structures specifically, simulation-based approaches have also been used to teach respiratory anatomy to students, with a low-cost bronchoscopy simulation reporting that a physical trainer carries theoretical respiratory anatomy into hands-on practice [3]. The pattern across that literature is consistent: the physical object does not add information, it adds engagement with the structure — and for microscopic structures shown at magnification, that is precisely the missing step.
The honest limit: BIX-A1069 is a static structural model. It does not demonstrate ventilation, gas exchange or compliance, and it does not show disease states. Ventilation and physiology must be taught by other means.
Q1. What is BIX-A1069?
An enlarged teaching model of a lung leaflet showing terminal bronchioles, respiratory bronchioles and alveolar epithelium.
Q2. How many parts does it have?
The page states 25 indicating parts.
Q3. What size is it?
28 x 21 x 14.5 cm, described on the page as enlarged.
Q4. Does it show the position of the lungs in the body?
No. It magnifies the functional unit. Position is taught on a torso or whole-lung model, which this model complements.
Q5. Does it demonstrate breathing or gas exchange?
No — it is a static structural model. It does not claim functional or pathological simulation.
Q6. How do I get the price and the part list?
Price is not published. Email cprmodel@adaanatomy.com with the model (BIX-A1069) and your quantity, and ask for the unit price, package dimensions and the list of the 25 indicating parts in the same message.
Write to cprmodel@adaanatomy.com for the BIX-A1069 specification sheet and a quotation. If you are building a respiratory teaching bench, ask in the same enquiry about the whole-lung models in this range so the sequence from position to functional unit is covered by one order and one labelling convention.
