This educational illustration depicts a cross-sectional view of the human heart, highlighting the four chambers (right atrium, right ventricle, left atrium, left ventricle), major valves (semilunar and atrioventricular), and connected vessels (aorta, pulmonary artery, anterior/posterior vena cava, pulmonary veins). The diagram uses distinct colors and precise labels to clarify blood flow pathways and structural relationships essential for understanding cardiac physiology.

Used in medical textbooks, online anatomy courses, healthcare training modules, and patient education materials; serves users seeking foundational knowledge of cardiovascular structure-students, educators, clinicians, and curious learners.
