Human Heart Anatomy Diagram - Educational Medical Illustration #2367989 (License: Personal Use)

This vibrant medical illustration depicts the human heart in cross-section, with color-coded chambers (red for oxygenated blood pathways, blue for deoxygenated), visible valves (mitral, tricuspid, aortic, pulmonary), and major vessels including the aorta, pulmonary artery, and vena cavae. The stylized but anatomically informed design makes complex cardiovascular anatomy accessible for teaching and patient education. Artist signature “MARTIN” and source credit “phillipmartin.info” appear subtly in the lower corners.

Used in educational websites, medical textbooks, health blogs, and classroom presentations to explain cardiac anatomy; targets students, teachers, clinicians, and patients seeking visual understanding of heart function and structure.
