Human Heart Blood Circulation Diagram - Chambers, Valves & Pathways #1203216 (License: Personal Use)

The image depicts the human circulatory pathway using a segmented circular diagram: yellow for right atrium (RA), blue for right ventricle (RV), green for left atrium (LA), and red for left ventricle (LV). Arrows indicate deoxygenated blood from the body/liver entering RA → RV → lungs, and oxygenated blood returning via LA → LV → systemic circulation. Key valves-mitral (M), aortic (A), tricuspid (T), and pulmonary (P)-are marked in yellow circles at chamber junctions.

Used in medical education, physiology textbooks, or health websites to explain cardiac anatomy and hemodynamics; targets students, clinicians, or patients seeking to understand heart function and blood flow direction.
