This high-resolution medical illustration displays a sagittal section of the human heart, clearly identifying the right and left atria and ventricles, pulmonary artery, aorta, superior and inferior vena cava, and heart valves including the mitral and tricuspid. Color coding distinguishes oxygenated (red) from deoxygenated (blue) blood pathways, supporting understanding of systemic and pulmonary circulation. Labels point to each critical structure for educational reference.

Used in medical textbooks, online anatomy courses, health education websites, and patient-facing materials to explain cardiac structure and function; matches user intent for studying or teaching cardiovascular anatomy.
