Which term describes the buildup of fatty deposits in arteries?

The term that describes the buildup of fatty deposits in arteries is indeed atherogenesis. Atherogenesis refers specifically to the process of plaque formation within the arterial walls, which primarily consists of lipids, cholesterol, and other cellular debris. This is the initial stage of atherosclerosis, a condition where these fatty deposits lead to the hardening and narrowing of the arteries.

In contrast, the term arteriosclerosis generally refers to the thickening and stiffening of arterial walls, which can be a result of several factors, including age and hypertension. It does not specifically denote the fatty buildup.

Arteriosclerosis is a broader term that encompasses various types of arterial stiffness, including atherosclerosis, while arteriopathy refers to any disease affecting the arteries without specifying the underlying causes or processes. Therefore, atherogenesis is the most accurate term for the process leading to the buildup of fatty deposits in arteries.
