This book is an attempt to bridge the widening gap between bioengineering, cardiovascular and clinical science and practice. It is based on a conference that included flow modelling in arteries and bypass grafts, concepts of fluid dynamics and turbulence in the system, and heomorheology and haemodnamics exploring factors that play a role in coronary circulations. This is a collection of papers from leaders in each of these and related fields and will be of major importance to anyone working in the mathematical or medical professions as an up-to-date treatment on the study of biological systems and their mathematical descriptions.
