The Heart

Overview

The heart is the central organ of the cardiovascular system, pumping blood through the pulmonary and systemic circulations. This section introduces its structural organisation and functional components.

Key Structures

Topics include the cardiac chambers, valves, conduction system, coronary arteries and veins, and the supporting pericardial structures. Each page outlines anatomy and core functional relationships.

Clinical Relevance and Learning Focus

Understanding cardiac anatomy is fundamental for diagnosing arrhythmias, valvular disease, ischaemia and heart failure. This section supports interpretation of ECGs, echocardiography and cross-sectional imaging, as well as clinical examination.
