befunky infografia de anatomía básica del corazón

Educational infographic poster titled "Basic Human Heart Anatomy" in portrait layout, with sharp readable text labels in clean sans-serif typography. Create a simple minimal corporate medical/anatomy infographic in monochrome black & white palette for an enthusiasts/technical audience, conceptual and non-graphic. Show 4 clearly numbered components arranged vertically with connecting arrows and subtle dotted guide lines, each number inside a black circle, sequence flowing from top to bottom.

1. heading: "Right Atrium", caption: "Receives low-oxygen blood returning from the body.", visual: clean simplified cutaway of the upper right heart chamber, with two major veins entering it, thin arrow icons pointing inward, and a small label line to the chamber.
2. heading: "Right Ventricle", caption: "Pumps blood toward the lungs for oxygen exchange.", visual: lower right chamber in the same heart cutaway, thicker muscular wall outline, bold directional arrow leading upward toward a simplified pulmonary artery diagram.
3. heading: "Left Atrium", caption: "Collects oxygen-rich blood coming back from the lungs.", visual: upper left chamber with two pulmonary veins entering, neat line-art vessel branches, and small inward arrows indicating return flow.
4. heading: "Left Ventricle", caption: "Sends oxygen-rich blood through the body.", visual: lower left chamber emphasized with the thickest wall in the cutaway, large arrow exiting into a simplified aorta arch diagram with small branching vessels.

Include a central simplified heart cutaway silhouette tying all four components together, with crisp leader lines from each numbered section to the exact chamber. Use thin vector arrows to indicate blood-flow direction between chambers and major vessels, plus a small monochrome legend with labels: "Low-oxygen flow" and "Oxygen-rich flow", differentiated by solid line versus dashed line, not by color. Keep composition airy, balanced, and highly legible, with precise anatomical simplification, clean icon-like diagrams, subtle panel dividers, and a professional technical editorial mood. Style: magazine-grade editorial illustration, vector-clean lines, no photographic textures. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
