This educational diagram depicts the human heart in anterior view, highlighting the four chambers (right/left atria and ventricles), major vessels (superior/inferior vena cava, pulmonary artery, aorta), and valves (tricuspid, mitral, pulmonary, aortic). Arrows indicate the path of deoxygenated and oxygenated blood through systemic and pulmonary circulation. The shading and labeling support visual learning for biology and medicine curricula.

Used in educational websites, e-learning modules, medical textbooks, and anatomy reference pages; serves users seeking to understand cardiac structure and function for academic, clinical, or self-study purposes.
