The Heart of the Matter

Did you know that cardiovascular disease (which includes heart disease) is the number one killer of men and women worldwide (WHO, 2012)? What lifestyle choices contribute to cardiovascular disease? How does contemporary culture make it difficult to conquer this disease?

Discussion: Homeostatic Imbalance in the Cardiovascular System

Every cell needs oxygen to live, and one of the primary roles of the red blood cells in your blood is to transport that oxygen throughout your body. When oxygen is consumed by your cells, it produces wastes, such as carbon dioxide, that are carried away by the bloodstream. Because the cardiovascular system nourishes all other systems and actively prevents the buildup of toxins, any health condition that affects the cardiovascular system will very likely impact your overall health as well. In this Discussion, you continue your exploration of a health condition and homeostatic imbalance through the lens of the cardiovascular system.

To prepare for this Discussion:

• Review the blood and cardiovascular system in the week’s Learning Resources. Investigate how your assigned health condition impacts those systems. Select the system that is most significantly impacted.
• Determine whether your health condition impacts the system you selected directly or indirectly. Most health conditions have a profound impact on only a few of the systems. Remember that the systems of the body work collaboratively as a single week. A lack of homeostasis in one system often leads to dysfunction in other systems as well.
• Keep in mind that the health conditions identified in this course are selected because they have a direct or indirect impact on at least one of the systems in each week of the course. If you are struggling to identify the impact of your assigned condition to any of the systems in that week, contact your Instructor for assistance.

With these thoughts in mind:

Post by Day 4 a 2- to 3-paragraph analysis that describes the impact of your health condition on one of the systems studied in this week. The analysis should:

• Explain whether the health condition has a direct or indirect effect on the system you chose, explaining why this system was impacted more than the other systems studied during this week.
• Describe how the pathology of the health condition causes a homeostatic imbalance in the system.
• Analyze the body’s reactions to the health condition as it attempts to re-establish homeostasis.
