ja+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.

Key terms: Lymphatic System Lymph Lymph Nodes White blood cells Lymph capillaries primary lymphoid organs secondary lymphoid organs spleen

Information gathered: The lymphatic system has 2 jobs, one is to return lost fluid from the blood back to the blood, the other is to defend the body against pathogens The lymphatic system goes all over the body because fluid is lost by capillaries all over the body The lymphatic system is made of vessels and is intermingled with the vessels and capillaries of the circulatory system Skeletal muscles move the lymph along The lymphatic system is used to remove any blood that spills over into the interstitual fluid due to an injury Lymph passes through lymph nodes and is scanned by WBC for pathogens. If pathogens are recognised, an immune response is triggered Lymph nodes are specialised structures where a large supply of white blood cells are found Lymoh nodes get swollen when WBC divide. Elephantiatis is a disease caused in part by the deterioration of the lymphatic system.

Structure of presenntation: The presentation as it stands will be divided up into three parts (after an initial introduction explaining what my topic is). The first part will have a focus on the lymphatic system itself, how is operates, what structures are specific to the system, what its underlying role in the immune response is. This addresses the first criterion. I'm hoping this will be 2-3 minutes worth of audio.

The second part will be focusing on the lymphatic system's link to self and non self thus linking it to the rest of the immune system which is criterion 2. As well as this, i plan to show how the lymphatic system is involved in specific responses and compare that to non-sepcific responses which also adresses criterion 2. I plan for this to be about 1 minute.

The thrid part will focus on the application of medicine to the functioning of the lymphatic system. i haven't started this yet but i hope that i will be able to find something really clear. 1 minute.

The different parts will be obviously seperate but there won't be a gap in the presentation or the audio. It will hopefully just flow one into the other. The order chosen for the presentation just addresses the assessment criteria in its order. The pictures (and i haven't done this yet) will reflect the concepts i am talking about or just be of the lymphatic system so that the viewer can picture what i am saying while i am saying it.

I found that elephantiatis is a disease caused by a damaged lymphatic system and other causes that all contribute to mass swelling and thickening of the skin. Scientists are trying to cure it by creating vaccines, doing surgery, using antibiotics, and rigourous cleaning sessions. I want to mention all of this in the presentation but unfortunately i don't know enough about it to satisfactorily explain how they are all effective. It is a good pathway to involve the medical application criterion.

Because the medical information is quite interesting and the lymphatic system itself doesn't need 3 minutes to be explained, the midecal application will consume more time than original predicitions.

In reflecting on this sac, i learnt a lot about the lymphatic system and how it operates and aids the body in the immune response. I would have liked to expand more on the ways in which medical affects the lymphatic system but due to the small time frame we had to work with i thought it smarter to just mention what techniques are being used to conquer problems with the lymphatic system rather than how those techniques can solve problems. I was happy that i could fit my presentation in the 5 minutes given and due to the additional criteria we had to deal with which may not have been so relevant to our specific topic (specific, non sepecific immune system, self and non self cells) im glad i was able to stick it all in. I just hope im not getting assessed on my entire knowledge of that stuff because i didn't want to go into it too much because my topic was the lymphatic system not the specific immune system. Overall, the structure was fine and i'm pretty satisfied with my effort.

Sequencing/choice of images: The images were just supposed to fit in with what i was talking about but i didn't want to find a new image for each detail becaue i was struggling to find good images at all so i just thought i would include general images that related to a whole area for instance: For the part about self and non self and the specific immune system, i just put up a picture of a T-lymphocte. I guess i'm hoping the focus will be on the audio rather than the pictures because i can talk but slideshow presentations aren't my forte. Together with the sectoin on the lymphatic system, i couldn't find images of lymph, blood vessels intertwined with lymph vessels, lymph vessels (that were clear). SO i just put up the general picture of the lymphatic system when talking about all its components and roles apart form the lymph nodes.
