Human Circulatory System Diagram - Blood Flow and Pressure Zones Explained #2089228 (License: Personal Use)

The image depicts a simplified yet anatomically accurate human circulatory system, with color-coded pathways-blue for deoxygenated blood and red for oxygenated blood-and labeled cardiac chambers (right atrium/ventricle, left atrium/ventricle), aorta, pulmonary arteries, and venae cavae. Pressure zones are clearly marked: highest pressure in the left ventricle/aorta, high pressure in pulmonary arteries, low pressure in pulmonary capillaries, and lowest pressure in the venae cavae. Arrows indicate direction of blood flow from systemic circulation back to the heart and into the lungs.

Used in medical education, physiology textbooks, health websites, and patient-facing resources to explain cardiovascular function; matches user intent for learning how blood pressure varies across the circulatory loop.
