Unit 12: Disease and Infection
This will form the final part of the research for Aim A
To achieve the Merit, you will need to focus on the non-infectious diseases. You must:
Choose a disease from each of the categories
- Dietary
- Environmental
- Genetic (include genetic cross diagrams and explanations)
- Degenerative
For each of the above categories name the disease and give a brief description of the type of
disease it is (e.g. this disease affects the liver, causing scarring and eventually liver disease)
Explain how the disease starts or how it develops (what caused it)
Describe how the disease affects the body
The section ‘describe what the disease does to disrupt the body’ - use the search term:
‘pathophysiology of [name of disease]’ to get the science behind how it affects body
systems and tissues.
You also need to explain the effects of the disease on the body. If it affects/targets a
particular organ why is that dangerous. E.g if the pathogen targets the lungs, why is that a
problem? What are the lungs important for? What is their role? What would happen if they
couldn’t work anymore?
Key terms: allele, homozygous, heterozygous, carrier, sufferer, gene
Asymptomatic, latency period, progressive, degenerative
To achieve the Distinction, you will need to
Explain and describe, in detail, how the disease progresses over time
Describe, in detail, how the disease affects a person’s ability to lead a normal life
For the distinction level tasks you need to ensure you have a full explanation and
description of the key points. Main focus is on how the disease will progress over time.
What are the stages the disease goes through? what is the life expectancy of the patient?
when does the disease start? Is there a latency period?
Also, you need to look at how your disease would affect the everyday life of a person. Is
there a lot of medication? Are there restrictions to what they can or cannot do? Do they
have to go to the hospital a lot? Would there diet be hugely affected?...full and detailed
explanations would need to be given
, Here is a template you can use to take notes and help with the content and order of your
task
DIETARY DISEASE
Name of disease
Brief introduction to the disease
How the disease is caused
How does the disease affect the body?
-what systems are affected? what organs
are affected? How does it disrupt the body
systems? What affects does this have on
the body?
Distinction
Explain how the disease progresses over
time
Explain how the disease affect a person’s
ability to lead a normal life?
