Human Circulatory System Diagram - Arteries, Veins, and Heart Anatomy #55544 (License: Personal Use)

This stylized anatomical diagram depicts the full human circulatory pathway, with red vessels indicating arteries (carrying oxygen-rich blood away from the heart) and blue vessels representing veins (returning oxygen-poor blood to the heart). The heart is centrally shown with distinct chambers, and the lungs appear as paired structures at the top, illustrating pulmonary circulation. A secondary red organ near the abdomen likely represents the liver or spleen, emphasizing systemic circulation.

Used in educational health content, medical textbooks, or patient-facing websites explaining cardiovascular anatomy; matches user intent for learning basic circulation, preparing for exams, or understanding heart-related conditions.
