atherosclerosis

This term describes a progressive biological degradation where the inner lining of the arteries becomes thickened and hardened. It carries a clinical, sterile tone, evoking an image of plumbing that has become clogged over time due to slow accumulation rather than a sudden blockage. While often used interchangeably with arteriosclerosis in casual conversation, this specific term emphasizes the role of plaque (atheromas) rather than general arterial stiffness. It is almost exclusively used in medical reports, academic journals, or diagnostic consultations.
