The cardiovascular system is the central engine of human life, driving circulation, maintaining homeostasis, and adapting to stress and disease. This book provides a comprehensive yet concise account of cardiovascular physiology, covering everything from the basic anatomy of the heart and blood vessels to the complex regulation of cardiac output, blood pressure, and regional circulation.

Special attention is given to clinical correlations such as heart sounds, ECG interpretation, arrhythmias, heart failure, shock, hypertension, and the physiology of exercise. Designed as a handbook-style resource, it is ideal for medical, dental, nursing, and allied health students preparing for examinations as well as for practitioners needing a quick refresher.

By the end of this book, readers will:

Understand the structure and function of the heart, vessels, and conduction system.

Learn how the cardiac cycle, heart sounds, and ECG reflect physiology in action.

Explore the mechanisms of cardiovascular regulation including Starling's law, autonomic influences, and RAAS.

Gain insight into regional circulations like coronary, cerebral, pulmonary, hepatic, renal, and fetal.

Apply physiology to clinical settings such as arrhythmias, hypertension, hemorrhage, and exercise adaptation.
