Human Heart Anatomy Diagram - Labeled Chambers, Valves & Blood Flow #1203217 (License: Personal Use)

This educational diagram depicts the four chambers of the human heart-right atrium (2), right ventricle (3), left atrium (8), and left ventricle (9)-along with major vessels including the aorta (1), pulmonary artery (6), superior vena cava (10), inferior vena cava (11), and pulmonary veins (7). Valves such as the tricuspid (4) and mitral (5) are clearly indicated, and the interventricular septum (12) separates the left and right ventricles. The blue and pink shading denotes deoxygenated and oxygenated blood pathways respectively.

Used in biology and medical education resources, anatomy textbooks, online learning modules, and health websites to teach cardiac structure and circulation. Matches user intent for visual learning, exam prep, or clinical reference.
