Explain activation and function of b cells in body defences | Homework Helpers

Case : Explain the activation and function of B cells in body defences. What are the mechanisms of antibody actions which support immunity? How does HIV infection impair the body’s ability to produce antibodies?

Assignment Structure:

The Assignment will have the following sections:

Introduction: An introduction should briefly describe the body system associated with the topic and identify its general role briefly. This should be followed by an identification of the factor/s influenced by the body system (in relation to the question) and why they need to be kept within a homeostatic range. Lastly, briefly describe what factor/s in the case disrupt homeostasis to cause disease. (75-100 words)

Body: The body of your descriptive piece expands on what was identified in the introduction. The mechanisms used by the body system to maintain homeostasis of the factor identified should be described. An explanation of how factors identified in the question disrupt the homeostatic mechanisms to cause disease should be provided and conclude with what could be expected to occur with such disruption. A final sentence should indicate that the processes identified are summarized in the following concept map. (400 words)

Summary Concept Map: Explained in the following slides.
A note on referencing: Appropriate in text referencing should be used along with the provision of a reference list. It is expected that 3-5 citations would be appropriate and that they are relatively recent (within the last 6 years). You should make use of your text book as a significant reference. **Use at least one journal article and NO website references-they are not reliable sources**

Assignment Overview:
This assignment will involve describing the physiological mechanisms in place for a particular body system to maintain homeostasis of a particular factor such as blood calcium, fluid volume, blood pressure etc. While normal functioning should be the main focus of the assignment it should; however, include a brief description of how homeostasis is disrupted leading to the appearance of disease identified in topic provided. Please note, the disease process is a minor focus. The assignment will also require the construction of a concept map that summarizes how a physiological system maintains homeostasis normally and how it can be disrupted to cause disease.

Assignment details

1. You will be allocated a topic and a list of student numbers with their allocated topic number for the case will be posted on the Blackboard site in week 3.

2. Submit assignment as a Word document, however, if you intend to use Power Point to produce your concept map and paste it into your word document. In order to copy your concept map, while in PowerPoint you will need to ‘group’ (In format tab) the whole map together and then copy and paste it into your word file as a picture. The written section should be about 500 words (+/- 15%) excluding references.

3. Following the initial written section your concept map should identify the central physiological mechanism in the case. Ensure that the relationship between the components are clearly identified and how they maintain homeostasis. The factors disrupting homeostasis and therefore causing disease need to be positioned appropriately in the concept map.

4. Check the assignment rubric to ensure you have covered all the required aspects.

5. Once your assignment is complete the file should be submitted to Turn It In. Instructions regarding access to Turn It In can be found on BB under “My Assessments”.
