Human Organ System

Critically evaluate the information provided, and correlate it with the organ systems that are affected in the
scenario. Use the information that you have gathered to answer the assignment questions that follow the case
study. Present your work as an APA-formatted research report.
Case Study 1:
Atherosclerosis is narrowing of the 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 suddenly 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 suffer a heart
attack.
Answer the following 3 questions in regard to this case study:
1.Provide a description of how the heart functions. Based on this, explain why atherosclerosis would result in a
heart attack.
2.How are arteries different from veins and capillaries? Describe the functions of arteries, veins, and
capillaries.
3.Vertebrates and some invertebrates have a closed circulatory system. Describe each of these. Explain the
advantage of having a closed circulatory system over an open circulatory system.
