One has to give it to Dr. Herlihy. She has done a good job with regard to The Human Body in Health and Illness. The book is very colorful and easier to read. She has paid attention to details. It has helped me in understanding human physiology and anatomy in a better manner when compared to other books. However, I felt some sections were vague and a bit confusing. If one can overlook that, then this is an excellent book.
