To anyone who takes the time to read this, I'm currently doing biology and only getting 'A's. I want to do much better but I always screw up somehow. I've got an assignment that I've done, but I'm not too confident about it. If you've got the time, please assess, critique and make any corrections that you see fit. Thanks for reading it. I'll just post the question sheet here:
This assessment task requires you to present in multimedia format an aspect of the immune response. This presentation must demonstrate:
• knowledge of the structure and function of the immune response
• understanding of the similarities and differences, in structure and function, of the non-specific and specific immune responses
• understanding of the concept of ‘self’ and ‘non-self’
• apply knowledge to one aspect of the immune system
FORMAT: Using Powerpoint or a poster you are required to answer the following questions in as much detail as possible, using diagrams, tables or graphs where applicable.
The immune system works on the basis of cells being able to recognize our own cells and those of foreign origin.
1. How do we differentiate between ‘self’ and ‘non-self’ cells? (3 marks)
The immune system reacts in a non-specific manner to any type of pathogenic agent.
2. Outline how:
a. skin and mucous membranes help prevent entry of foreign agents (1 mark)
b. phagocytes and complement proteins react to entry of pathogenic agents. (5 marks)
The specific immune response is different in a number of ways from the non-specific response.
3. Using a table briefly outline these differences. (3 marks)
4. Using a flow diagram describe the interaction between pathogens, macrophages, T-cells and B-cells in the specific immune response. (6 marks)
The knowledge and understanding of how the specific immune system works has enabled us to combat and, in many cases prevent serious disease outbreaks. The main weapon in this is providing the community with immunity to many diseases caused by pathogenic agents. The active induced immunity obtained by a program of vaccinations during the first 14-15 years of life has almost eliminated any cases of these diseases in Australia.
5. Choose a particular disease we are currently vaccinated against and describe
a. What the components of the vaccine are. (1 mark)
b. How this provides protection against the disease. (4 marks)
2 marks for the bibliography, referencing. Assignment attached below.
