Human Circulatory System Diagram - Arteries, Veins, and Capillary Networks #1438730 (License: Personal Use)

The diagram depicts a simplified yet accurate representation of microcirculation, where a larger artery (A) bifurcates into smaller arterioles (B), feeding a capillary network (C) for nutrient and gas exchange. Blood then drains through venules (D) into a collecting vein (E). Black segments indicate direction of blood flow or vessel occlusion sites in clinical contexts.

Used in medical textbooks, physiology lectures, and online health education to explain vascular anatomy and hemodynamics; supports user intent for learning circulatory structure or diagnosing vascular pathologies.
