plastic bone

Answer 1

Best answer: plastic bone.

Why: a plastic (anatomical) bone model commonly includes a cross-section showing the marrow cavity where hematopoiesis occurs, so it directly shows the site and structure involved in blood‑cell formation.

Notes on the others:
- Photograph of a bone: usually just shows the exterior, not the marrow.
- Dissected pig: can show real tissue and marrow but is messy, variable and not as clear for teaching the specific process.
- Computer‑generated model: excellent for showing dynamic steps of hematopoiesis (lineages, cell stages) but only if it’s specifically designed for that purpose.
