Solution-Different from veins and capillaries | Homework Help

Atherosclerosis is narrowing of arteries caused by the accumulation of fatty deposits on the arterial walls. On June 22, 2002 the St. Louis Cardinals were preparing for their upcoming baseball game against the Chicago cubs. Concern arose when their prized pitcher, 33-year old Darryl Kile did not show up for practice. Soon after, he was found still in his hotel room where he had suIDenly died in his sleep (New York Times, 2002). It was discovered that the cause of death was related to three of his coronary arteries being 80-90% blocked as a result of atherosclerosis (New York Times, 2002), which ultimately caused him to undergo a heart attack.
