Atherosclerosis is a disease in which plaque builds up inside arteries causing hardening and narrowing of the arteries. Consequentially, arteries are silently and slowly blocked. This puts blood flow at risk. Therefore we can conclude that Atherosclerosis probably contributes to hypertension by causing arteries to become narrower.
John Locke was the philosopher who maintained that knowledge comes from experience via the senses, and therefore, science should rely on obersvations and experiments.
