The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered.
For this assignment, make sure you post your initial response to the Discussion Area by Saturday, December 14, 2013.
To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format.
Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Complete your participation for this assignment by Wednesday, December 18, 2013.
Viruses and Homeostasis
Using the South University Online Library or the Internet, research about viruses and homeostasis. Based on your research and understanding, provide your response to the following tasks:
1. Analyze the feedback mechanisms that maintain homeostasis, and what happens when these systems do not function appropriately. Provide two specific examples for each.
When the human body contains a stable, reliable, and harmonious environment this is known as homeostasis, (Martini, 2009, ch.1, 1-6, pg.12). The makeup of homeostasis consists of negative feedback and positive feedback. Negative feedback is the primary mechanism that corrects and regulates the environment inside of the body, (Martini, 2009, ch.1, 1-6, pg.14). Positive feedback is important in the process of regulating the environment of the body, because positive feedback accelerates the process of healing and fixing the environment inside of the body, (Martini, 2009, ch.1, 1-6, pg.16). One example of a feedback mechanisms not functioning correctly would be when someone gets a sinus infection and they get to where they cannot stand up without getting help. Another example of feedback mechanisms not functioning correctly would be when a baby is born with down syndrome, showing that the feedback mechanisms were not working completely while the mother was pregnant, (Martini, 2009, ch.1, 1-6, pg.16).
2. Provide the organizational levels in order, beginning at the atom. Then, analyze how each level relates to specific functions and to each other.
