Prompt
A single continuous black ink line drawing of an anatomical human heart on plain white paper, one unbroken stroke forming the left and right ventricles, the aorta arching upward, the pulmonary trunk, the superior vena cava, and the coronary arteries branching across the surface, the line never lifting from the page and never crossing itself, thin even line weight throughout, no shading, no color fill, no gradients, generous white margin, medical illustration lineage, no text, no letters, no labels --ar 2:3 --stylize 100

How to use this prompt
"One unbroken stroke" and "the line never lifting from the page" are the two phrases that hold the continuous-line premise — without them Midjourney adds pen lifts and separate strokes that break the single-line contract. Naming the heart's external anatomy explicitly (aorta arching upward, coronary arteries branching, superior vena cava) gives the model the structure it needs rather than hoping it remembers the shape. "Never crossing itself" is the other constraint that separates a true continuous line from a scribble; crossings read as rendering errors. Stylize 100 is the ceiling for this style — higher values add ornamental flourishes that fight the clinical premise. The 2:3 portrait suits a framed print.
Variations to try
- Redraw as an anatomical brain in continuous line, the gyri and sulci traced in one stroke
- Recolour the line to deep crimson on warm off-white for a medical-textbook feel while keeping the single stroke
