rd+immune+SAC

One of the criteria for the immune response SAC requires you to show your progress in developing your presentation. On this page you should have the following. You should show your planning of the presentation, such as the images chosen and information you want to convey. This includes how you broke up your topic into the various sections. You should also include why you sequenced the images the way you did and the collating of information. It is important that you acknowledge any sources of information (including images) below. You will also need to upload your audio file onto this page.

Initially I wanted to describe the whole non specific immunity section of the immune system. However with the five minute time constraint i would not have adequate time and would be unable to go in to detail. Instead i chose just to discuss the first line of defence. I wanted to give a few in depth descriptions of __some__ of the elements of our first line of defence. To describe all of them would take too long. I broke up the first line of defence into 3 aspects: chemical barriers, physical barriers and natural flora. In my examples of these i aimed to convey how they worked, and emphasise, the main aim of the first line of defence: to prevent potentially dangerous foreign materials entry into the internal environment of an organism where they can cause sufficient damage (ectoparasites were not explicitly mentioned - but it should be thought that parts of first line of defence (eg salt in sweat) wold inhibit these parasites growth on skin). I intended listeners to gain this insight into the first line of defence and fromt here understand how it contributes to the immune systems fight againt pathogens in quite a simplistic manner - by preventing pathogens entry into the body.

The analogy of a castle was used to help convey this understanding to listeners. Likewise, the visual images were intended to act as cues to aid this understanding. However, the main body of information was intended to be interpreted via sound. The main message of the media presentation (first line of defence = keep pathogens out) was hopefully conveyed through the image of pathogens on one side of the line (external environment) and no pathogens on the other line (internal environment) with the line itself signifying the barriers in the first line of defence to prevent microorganisms invasion. This is the reason this image was repeated several times in the display.

Other images used were of less significance, but rather as a tool to enhance the audiences recognition of the concepts being discussed.

At the end of the presentation, I tried to reinforce the fact that the first line of defence's preventative exclusion of all material occurs in a manner that does not use the body's other intricate methods of detecting self and non-self. The reason for this being logical, that there is no need to detect self and non self in our external environment, as none of us exists in our external environment which is self.
