Human Heart Anatomy and Blood Circulation Explained #55545 (License: Personal Use)

This medical illustration depicts the four chambers of the human heart-right atrium, right ventricle, left atrium, and left ventricle-with precise labeling of valves, the aorta, and pulmonary vessels. Arrows indicate the path of deoxygenated blood entering from the body to the right side, then to the lungs for oxygenation, and oxygen-rich blood returning to the left side for systemic distribution. The diagram highlights functional separation between pulmonary and systemic circulation loops.

Used in educational websites, biology textbooks, health portals, and medical training materials to explain cardiac physiology; targets students, teachers, and patients seeking foundational cardiovascular knowledge.
