1)What is the medical term for the hardening of arteries and what does it mean?The medical term for the hardening of the arteries is arteriosclerosis. It is when there is a build up of fatty deposits on the inner lining of the arterial wall. The deposits reduce the normal flow of the blood through the artery.
