This anatomical illustration depicts the human heart’s four chambers-left and right atria and ventricles-along with major vessels including the aorta, pulmonary artery, superior and inferior vena cava, and pulmonary veins. Arteries are colored red to indicate oxygen-rich blood flow, while veins are blue for deoxygenated blood, supporting visual learning of systemic and pulmonary circulation. The image emphasizes structural relationships critical for understanding cardiac function and pathology.
