Blandine Calais-Germain is an extremely talented person. As part of my Pilates training, I read her Anatomyof Movement, which is an excellent, informative book with beautiful illustrations she did using dancers as models. Anatomy of Breathing explores the structures and functions of one of our basic activities with the same thoroughness and grace.
In addition to the explanations of which bones and muscles are involved, she provides discussions of why different kinds of breathing are useful in different situations and exercises that allow the reader to explore those options.
Whether one is interested in anatomy, mindfulness, or performance, this book is a valuable resource.
