Immune System Response Infographic | Anatomy of Female Abdomen

Biological diagram infographic titled "Immune System Response" centered around a clean labeled pathway-flow diagram showing a simple, kid-friendly overview of how the human immune system responds to a germ, with directional arrows from entry of pathogen to detection, defense, and memory formation. Use a central editorial scientific illustration of a human body silhouette with simplified internal immune organs and enlarged inset pathway elements for cells and antibodies, scientifically accurate but easy to understand for ages 8-12. Add 7 labeled components arranged neatly around the central diagram, each connected by a thin leader line, each with a short label in English and a one-line function description in English. Include these exact labels and captions: "Pathogen" — "A germ enters the body and may cause infection."; "Skin and Mucosa" — "These barriers help block germs from getting inside."; "Macrophage" — "This white blood cell engulfs and breaks down invaders."; "Lymph Node" — "This filter site helps immune cells meet and activate."; "T Cell" — "This cell coordinates the immune response and kills infected cells."; "B Cell" — "This cell makes antibodies against specific germs."; "Antibodies and Memory Cells" — "These proteins and cells help stop the germ faster next time." Show input → output markers such as "Germ enters" to "Protection and memory" within the flow layout. Visual style: medical illustration, Netter-style educational anatomy, editorial scientific infographic, simplified for children, anatomically tasteful, smooth shading with vector-clean lines. Color palette: monochrome scientific palette using grayscale, soft charcoal, pale silver, and muted slate tones. Overall mood: calm, clear, educational, reassuring, precise. Ensure all text is sharp and readable, with balanced spacing and uncluttered composition. 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.
