The aim of this book is to be a core textbook of anatomy and physiology in childbearing. Written to present childbearing in the context of changes to non-pregnant physiology, therefore, both anatomy and physiology, their changes in pregnancy, and pathophysiology are all described. The book is divided into four sections - preconception, pregnancy, labour and puerperium - and it places childbearing in a total biological context so that concepts are drawn from disciplines such as evolution, ecology, biochemistry and cell biology. At all times, the text is related to practice and care giving.
