Atherosclerosis - Definition
Atherosclerosis (pronounced ath-uh-ro-skluh-RO-siss) is the build-up of a waxy deposit on the inside of blood vessels. Atherosclerosis is a form of arteriosclerosis (pronounced ar-tir-ee-o-skluh-RO-siss). Arteriosclerosis refers to any condition in which the arteries become hard and less flexible. The two terms are often used interchangeably, although it is not really correct to do so.
