Whether diagnosing diseases, performing life-saving surgery or fighting a pandemic, doctors do a huge variety of jobs. Join them in remote research stations, operating theatres, medical laboratories and hospitals to discover what they do and why it's so important. From heart transplants to investigating a crime scene, you'll encounter all kinds of examples of doctors' extraordinary everyday work. And at the back of the book, there's a glossary of medical terms, diagrams of the body's bones and organs, plus information on what to do if you want to become a doctor yourself one day.
