How Your Immune System Works

You hear about T cells, antibodies and inflammation all the time. Every explanation seems to assume you already sat through a biology class, so the words wash over you and nothing sticks.

This audiobook explains your immune system from the ground up through one picture you can hold in your head the whole way. Your body is a sprawling city. Skin forms its walls and neutrophils rush in as first responders. Macrophages clean the streets, T cells work as special forces and B cells run the weapons factories. Memory cells keep the city archive. Each chapter is commute-sized and built around a moment that makes you stop and think. Big numbers come with everyday comparisons so they feel real. A spoken recap closes every chapter, followed by a calm look at what scientists know and what they are still working out.

By the end you can follow the news, a doctor's explanation or a dinner-table debate and understand what your body is actually doing. Press play on your next walk and meet the city that keeps you alive.
