Welcome to my illustrated guide to the immune system. I hope you enjoy reading it as much as I have had writing and illustrating it and that the immune cells protecting our bodies become as real to you as they do to me.

Make your way to the contents section and you will find links to all the chapters. The whole text can easily be downloaded in a PDF version. If the book is downloaded, would you consider making a small donation of about £3.00 by clicking the PayPal button. Many thanks.
