Your body's defense network — a sophisticated layered system that detects, neutralizes, and remembers threats. From physical barriers to adaptive memory, it operates 24/7 without you noticing.

Tap viruses and pathogens before they breach your barrier. Each level teaches a different immune mechanism — from mucus and cilia to antibodies and T cell memory.

Phase 1: Foundational Defenses — physical barriers, innate immunity, and early adaptive responses including B cells and T cell memory. Phase 2: Advanced Immunity — immune regulation, tolerance, complement cascades, and vaccine-enhanced memory responses.
