Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #3365136 (License: Personal Use)

This educational diagram shows the four chambers of the heart (right atrium, right ventricle, left atrium, left ventricle), the four main valves (tricuspid, pulmonary, mitral, aortic), and major vessels including the superior/inferior vena cava, pulmonary arteries/veins, and aorta. Arrows indicate deoxygenated blood entering via vena cava to the right side, oxygenated blood returning via pulmonary veins to the left side, and systemic circulation through the aorta. The color-coding (blue for deoxygenated, red for oxygenated) enhances visual comprehension.

Used in biology, anatomy, and medical education resources-especially on websites, textbooks, or e-learning platforms-to help learners visualize cardiac structure and hemodynamics. Matches user intent for studying heart function, preparing for exams, or teaching circulatory system basics.
