Prompt:
A detailed and anatomically correct image of human heart with all its vessels accurately labeled. The heart should be depicted in a realistic manner, not stylized or abstract. The vessels, including the aorta, venae cavae, pulmonary veins, and arteries should be clearly visible and marked with their names. The colors used should mirror those found in standard medical illustrations: red for oxygenated blood vessels, blue for deoxygenated, and the heart itself shown in a deep natural red. The labels should be easy to read, preferably in a black, simple, and bold font.
