Prompt: Create a 10-second ultra-realistic 3D medical animation based on the reference infographic showing the site of hemoglobin formation. Start inside the red bone marrow, where a polychromatophilic erythroblast gradually transforms into an orthochromatic erythroblast, then into a reticulocyte as bright red hemoglobin accumulates inside the cell. The camera smoothly follows the reticulocyte as it exits the bone marrow into the bloodstream, where it continues producing a small amount of hemoglobin for 1–2 days before maturing into a biconcave erythrocyte (mature red blood cell). Display clean scientific labels: "Bone Marrow", "Reticulocyte", "Bloodstream", and "Mature RBC". Use cinematic lighting, realistic cell textures, smooth camera motion, shallow depth of field, glowing hemoglobin particles, and professional medical visualization in 4K UHD, educational style. Voiceover (10 sec): "Hemoglobin synthesis begins in developing red blood cells within the bone marrow. It continues briefly in circulating reticulocytes before stopping as they mature into fully functional red blood cells." Audio / SFX: Soft cinematic ambient music. Gentle cellular humming. Subtle whoosh during camera transitions. Light heartbeat and blood-flow sound in the bloodstream. Soft sparkle/chime as the mature red blood cell forms.
