Art style: 3D Medical Animation.
A realistic human heart at the center of the frame, deep crimson and glistening, surrounded by branching arteries filled with clear, translucent red fluid. Inside the vessels, individual disc-shaped red blood cells flow in orderly streams. Medium close-up, slightly low angle emphasizing the heart's strength. Warm, soft directional lighting with amber and rose highlights casting gentle glow across the muscular surface. A vital, healthy, reassuring atmosphere. Dominant palette of rich red, warm pink, and soft golden highlights against a dark neutral background.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Medical Animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Medical Animation". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "3D Medical Animation" idiom, not in any other medium.
