"A highly detailed, medically accurate anatomical diagram of the human heart. The heart is shown from an anterior (front) view with a clean, professional medical illustration style on a solid white background. Each major part is clearly distinct with slightly different realistic textures and colors. Use thin, straight black leader lines pointing exactly to the specific parts. At the end of each line, include clear, legible labels in a simple sans-serif font for the following parts: Aorta, Superior Vena Cava, Left Atrium, Right Atrium, Left Ventricle, Right Ventricle, Pulmonary Artery, and Pulmonary Veins. Ensure the labels are arranged neatly around the heart without overlapping. 8k resolution, scientific poster aesthetic."
