Immune System Response Infographic | heart internal structure

Biological diagram infographic titled "Immune System Response". Center the composition around a clean LABELED DIAGRAM showing an immune response pathway flow integrated with a simplified human anatomical context: upper airway / tissue entry site at left, draining lymph node at center, blood vessel and infected tissue at right, with clear directional arrows showing pathogen entry → antigen capture → lymphocyte activation → effector response → resolution. Use an editorial-grade medical illustration (Netter-style) with biologically accurate human anatomy and immune cell morphology, professional for a medical audience. Add exactly 7 labeled components arranged evenly around the central diagram, each with a thin leader line, a short label in English, and a one-line function description in English. Labels to render exactly as: 1. "Pathogen Entry" — "Microbes breach epithelial barriers and initiate innate immune recognition." 2. "Dendritic Cell" — "Captures antigen in tissue and migrates to the lymph node for presentation." 3. "Lymph Node" — "Site where antigen presentation activates adaptive immune cells." 4. "Helper T Cell" — "Coordinates immune signaling and promotes B-cell and cytotoxic responses." 5. "B Cell / Plasma Cell" — "Produces antigen-specific antibodies that neutralize extracellular targets." 6. "Cytotoxic T Cell" — "Recognizes and destroys infected host cells displaying foreign antigen." 7. "Memory Cell" — "Persists after infection to enable faster and stronger secondary responses." Include small input and output markers along the flow: "Antigen" at entry and "Pathogen Clearance" at resolution. Render subtle inset cellular details for antigen presentation, antibody release, and target-cell killing, while keeping the overall layout clean and readable. Visual style: medical-textbook plate, Netter-style anatomical rendering, monochrome scientific palette using charcoal, slate gray, soft ivory, and cool gray accents; calm, clinical, high-clarity mood; balanced negative space; crisp typography; sharp readable labels. 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.
