This book provides a highly accessible introduction to anatomy and physiology. Written for students studying the subject for the first time, it covers the human body from the atomic and cellular levels through to all the major systems and includes chapters on blood, immunity and homeostasis. Logically presented, the chapters build on each other and are designed to develop the reader's knowledge and understanding of the human body. By the end of each chapter, the reader will understand and be able to explain how the structures and systems described are organised and contribute to the maintenance of health. Describing how illness and disease undermine the body's ability to maintain homeostasis, this text helps readers to predict and account for the consequences when this occurs. Complete with self-test questions, full colour illustrations and a comprehensive glossary, this book is an essential read for all nursing and healthcare students in both further and higher education.
