The Biomedical Sciences Explained series has been designed specifically to meet the needs of today's undergraduates studying biomedical sciences. Each volume in the series covers a key biomedical science topic, enabling the student to select the volumes required for their chosen topics, and build up their own 'personal textbook' in biomedical sciences. Using the BMS Explained Series students can build up their own 'personal textbook' in biomedical sciences, written specifically for them, rather than buying an enormous textbook which is too detailed when only studying a topic for one or two modules. Each volume provides a core of knowledge from which the student can then go on to more advanced study in their chosen subject. 'Haematology' emphasizes the scientific principles which underpin our understanding of the blood in health and disease. It seeks to integrate knowledge of biochemistry, physiology, genetics and cell biology and apply them to the study of the blood, although little prior knowledge is assumed.
