Overview
The cardiovascular system circulates blood to deliver oxygen and nutrients throughout the body. It consists of the heart arteries veins and capillaries working in a coordinated manner. Proper function is essential for tissue perfusion and homeostasis.
Heart Structure
The heart has four chambers two atria and two ventricles separated by valves. Myocardium and conduction tissue support pumping and rhythm. Coronary arteries supply the heart muscle itself.
Vascular Network
Arteries carry oxygenated blood away from the heart and veins return deoxygenated blood. Capillaries enable exchange of gases nutrients and waste at the tissue level. Vascular tone and integrity regulate blood pressure and flow.
Clinical Relevance
Cardiovascular disease includes ischemic heart disease heart failure and hypertension. Imaging modalities assess structure function and perfusion for diagnosis and management. Early detection and risk modification improve outcomes.
