Human Embryonic Development Infographic for Science Poster

Biological diagram infographic titled "Stages of Human Embryonic Development" centered on a clean labeled circular life-cycle diagram showing human embryonic development from fertilization through early fetal stage, arranged as a clockwise developmental ring with subtle directional arrows between stages. Place 7 labeled stages evenly around the central diagram, each with a thin leader line, a short label in English, and a one-line function description in English. Use biologically accurate proportions for each stage and tasteful educational presentation for a curious enthusiast audience. Labels to render exactly as: "Zygote" — "Single fertilized cell that contains the complete genetic blueprint."; "Cleavage" — "Rapid cell divisions increase cell number without increasing overall size."; "Morula" — "Solid ball of blastomeres formed during early embryonic division."; "Blastocyst" — "Hollow stage that prepares for implantation into the uterine lining."; "Implantation" — "Embryo attaches to the endometrium and begins maternal exchange."; "Gastrulation" — "Three germ layers form and establish the basic body plan."; "Early Organogenesis" — "Major organs, including the early heart and lungs, begin to develop." In the center, show a refined summary embryo silhouette and small inset cues for germ layer formation and early organ development, with circular flow emphasis rather than a cross-section. Add small unobtrusive input-output style markers for timeline progression: "Fertilization" at the start and "Early fetus" at the end. Visual style: medical illustration, Netter-style, editorial scientific plate, precise anatomical draftsmanship, soft ink shading, monochrome scientific palette with charcoal, graphite, slate gray, and pale ivory background, calm academic mood, high contrast sharp readable typography. Include medical-textbook clarity, editorial scientific 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 graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
