Human Organ Systems
Organs in the human body function as part of an integrated group of structures known as organ systems. Examples of organ systems are as follows:
Cardiovascular system
Digestive system
Musculoskeletal system
Nervous system
Excretory system
Endocrine system
Respiratory system
These organ systems are responsible for crucial processes necessary for sustaining life, often working together, interacting with other organs in a functional network that keeps the body in balance (homeostasis). When homeostasis (the normal functioning of organ systems) is disrupted, disease may develop, causing injury to the body or even death. Watch this video for help with completing the assignment.
Choose 1 case study to explore a disease or organ malfunction:
Case Study 1 (Heart attack)
Case Study 2 (Lung cancer)
Click on the case study of your choice above to view the questions for that topic. Present your answers to the questions in the form of a 2–3-page paper.
Utilize at least 2 credible sources to support the arguments presented in the paper. Make sure that you cite them appropriately within your paper, and list the references in APA format on your Reference page.
Refer to your assigned textbook Concepts in Biology, Chapter 16.3: Circulatory and Respiratory Systems for help.
Formatting guidelines: In accordance with APA formatting requirements, your paper should include Title and Reference pages; should be double-spaced; and should include a running head and page numbers. Your paper should be 2–3 pages in length, not counting the Title page, and Reference page.

Unit 4 IP Case Study 1 (Heart Attack)
Atherosclerosis is the 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 in his hotel room, where he had died in his sleep. 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, which ultimately caused him to suffer a heart attack. (Altman, 2002)
Address the following regarding 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; most invertebrates have an open circulatory system. Describe both open and closed circulatory systems. Explain the advantage of having a closed circulatory system over an open circulatory system.

Unit 4 IP: Case Study 2 (Lung Cancer)
Cigarette smoking remains the leading preventable cause of death in the United States, causing an estimated 438,000 deaths—or about 1 out of every 5 smokers—each year (Woloshin et al., 2008).
Mr. Amos is 57 years old and has been smoking for the past 30 years of his life. A recent doctor’s visit revealed that Mr. Amos has stage 3 lung cancer, characterized by his symptoms of nagging chest pain, fatigue, coughing up blood, substantial weight loss, and increased blood carbon dioxide levels. The doctor informed Mr. Amos that had he quit his smoking habit several years ago, he would have reduced his risk for developing lung cancer later in life. Mr. Amos immediately began treatment for the lung cancer that had metastasized to his lymph nodes.
Answer the following 3 questions regarding this case study:
1. Briefly describe the respiratory system. What main components in cigarettes affect the respiratory system? Explain the effect of 2 compounds from cigarette smoke on specific organs, cells, and processes in the respiratory system.
2. There are alternate mechanisms of transporting carbon dioxide (CO2) and oxygen (O2) in the blood. Explain how smoking might lead to increased levels of carbon dioxide in the blood.
3. Can smoking affect other organ systems of the body? Give specific examples, and briefly explain your answer.
