Generate an ultra-realistic cross-sectional image of a human artery showing severe atherosclerosis. The artery walls should appear textured and lifelike, colored in a deep red, and lined with thick, yellowish plaque buildup that narrows the artery's lumen significantly. The image should emphasize the dangerous obstruction to blood flow by depicting a large, almost-detached blood clot (thrombus) precariously attached to the plaque, along with a few smaller clots scattered nearby. The blood clots should be dark, textured, and appear as a serious threat to blood flow, with a focus on the realistic portrayal of the artery's interior structure, including the texture of the clots and the rough, uneven plaque deposits, This image provides a close-up view inside a human artery. It depicts a cross-section that reveals the layers of the arterial wall, showing a build-up of cholesterol or plaque deposits that threaten to impede blood flow. The textures and colors capture the intricate biological structures in vivid detail, emphasizing the health risks associated with arterial blockages
