A student-friendly guide

Pathophysiology

explained plainly, learned by doing

A pathophysiology book for the way people actually learn: every idea in plain English first, then an interactive you can click, drag, and play with — so the mechanism sticks instead of just the words.

by Dr. Akash Garg
📖 A note: the book follows the course — one chapter per week — and each chapter ends with that unit’s flashcard deck and its interactive labs. Chapters marked Ready are live now; the rest are on the way (Week 7 is midterm review). Start with the ready one below to see how it works.
