This image features a highly detailed, three-dimensional anatomical model of the human heart, rendered for medical and scientific purposes. The intricate structure clearly displays the heart muscle (myocardium) in shades of red and pink, while the major arteries and veins of the cardiovascular system are distinctly colored blue and red for easy identification. Set against a dark, technical background with a subtle grid overlay, the model emphasizes the complex vasculature and external anatomy, making it an excellent resource for medical education, patient visualization, and physiological study.
