A highly detailed biological illustration of a centaur, showing its internal anatomy with human torso integrated into the horse's withers in a scientific diagram style.

"Create a high-realism biological illustration of a centaur. The lower, equine half is anatomically dominant, housing all major organs, including the respiratory system and lungs, which are positioned in its abdomen. The upper, human half is integrated into the horse's withers, featuring an open, minimized chest cavity with no human-scale heart or lungs. To maintain the human torso and arm strength despite low blood pressure, the upper half is supported by a dense network of powerful, reinforced veins. The entire structure emphasizes the seamless and logical, though non-traditional, biological fusion, rather than a mythological aesthetic. The art style should be a detailed, scientific diagram, showing the internal organ layout." See more
