Unit 2: Health Issues and Scientific Reporting deck, 47 slides

the Unit 2 section of the spec (A1–A2, B1–B2, C1–C2, D1–D3, E1–E3). I

What’s in it:

Introduction (5 slides): the box key, the five content areas, the exam with all four AOs, and the eight command words, including “Show”.
A: Diagnostics (9 slides):
A “vital signs at a glance” table: method, normal range and what an abnormal result may suggest.
Heart rate, with a drawn ECG and a heart-rate calculation.
Blood pressure, with a worked hypertension example.
Spirometry and peak flow, with an FEV₁/FVC calculation and asthma vs COPD.
Temperature, capillary refill and oxygen saturation.
Nerve tests, with a conduction velocity calculation.
Amniocentesis vs CVS, with ethics.
An “Explain” model using test results.
B: Immunity (11 slides):
Innate defences, and inflammation (acute vs chronic).
Six steps of adaptive immunity, and a primary vs secondary antibody response chart with passive immunity.
Autoimmune tests.
Every condition the spec lists, set out in causes / symptoms / impact / treatment panels:
Autoimmune: MS, Crohn’s and rheumatoid arthritis.
Immunodeficiency: SCID, HIV, chemotherapy and transplants.
Allergies: allergic asthma, anaphylaxis and dermatitis.
Ethics of transplants and transfusions.
C: Genetics (6 slides):
Transcription, splicing and translation, and the three mutation types with base-sequence examples.
Hereditary vs acquired mutations.
Inheritance terms, with drawn Punnett squares for cystic fibrosis and Huntington’s, plus haemophilia outcomes.
The four conditions, and DNA sampling, sequencing and genomic data ethics.
D: Cancer (6 slides): causes (mutagens, tumour suppressors, oncogenes), benign vs malignant, diagnosis methods, the three screening programmes with benefits and risks, a treatment table with short- and long-term effects, and a “Discuss” model.
E: Scientific information (7 slides):
Quantitative vs qualitative evidence, and data collection methods.
Worked averages and percentage change, plus standard deviation, significance and uncertainty.
A scatter chart for describing and explaining trends (correlation vs causation).
Validity factors, and organisations, error types and source reliability.
A judgement model.
Review (4 slides): exam technique, a key words check, a confidence tracker and a “Well done” slide.
