Cardiovascular Physiology,eighth edition,offers the fundamentals in a fast,clear,and concise manner.It provides a basic understanding of how the cardiovascular system functions in health and disease.This new eighth edition of Cardiovascular Physiology is the ideal tool for learning those basics. Look at the following outstanding features: Includes a wealth of new topics,such as delayed rectifier K channels and their importance in cardiac dysrhythmias,nitric oxide in the regulation of vascular resistance,mechanisms in the divelopment of the collateral circulation,effects of ischemia on the Na/Ca exchange,and much more. New information on the importance of preload and afterload in determining cardiac performance. New student-friendly tools,including Statement Headings and Chapter Objectives. Now includes Clinical Case Studies with multiple-choice questions,answers,and rationales. Updated illustrations and bibliographies throughout.
