Sectional View of the Human Heart - Anatomy Diagram with Labeled Chambers & Vessels #1664340 (License: Personal Use)

This educational illustration depicts a sagittal cross-section of the human heart, distinguishing oxygen-poor (blue) and oxygen-rich (yellow/tan) blood pathways. Key labeled components include the right and left atria and ventricles, the interventricular septum, aorta, superior and inferior vena cava, and pulmonary arteries and veins, with directional arrows indicating circulation. The drawing emphasizes functional anatomy for students and clinicians learning cardiac physiology.

Used in medical textbooks, online anatomy courses, health education websites, and classroom presentations to teach cardiovascular structure and systemic/pulmonary circulation; targets learners seeking visual reinforcement of heart anatomy.
