First 184 words of the document:

Keeping healthy involves maintaining a healthy lifestyle, avoiding infection, and using medication when necessary. This module illustrates these
principles through prevention of infectious diseases and heart disease.
You will learn about the immune system, and how vaccines work to prevent infection. You will also learn about the increase of `superbugs', and
how correct use of antibiotics can help to reduce their prevalence. The module explores how new drugs are developed, including the stages of
testing for safety and effectiveness. You will also consider the causes of heart disease, and how individuals can minimise this risk. You will also
learn about maintaining a constant internal environment, illustrated through how our body keeps a healthy water balance. In the contexts of
vaccination policy and the study of clinical trials, you will explore ideas of correlation and cause, and how peer review by the scientific community
strengthens the confidence in scientific claims. You will also consider particular ethical issues arising in modern medicine, for example, the right
of individual choice versus social policy, illustrated through vaccination policy.

B2.1 How do our bodies resist infection? Y/N EVIDENCE
1. Can I describe how symptoms of an infectious disease are caused
by damage done to cells by microorganisms or the poisons (toxins)
they produce?
2. Can I explain why, in suitable conditions such as those inside a
human body, microorganisms (eg bacteria and viruses) can reproduce
rapidly to produce very large numbers?
3. Can I calculate the population growth of microorganisms given
appropriate data?

Can I describe why vaccines and drugs (medicines) can never be
completely riskfree, since individuals have varying degrees of side
effects to them?
5. Can I explain why due to genetic differences, people react differently
to drugs and vaccines?
6. Can I explain how chemicals called antimicrobials can be used to
kill, or inhibit, bacteria, fungi and viruses
7. Can I remember that antibiotics are a type of antimicrobial that are
effective against bacteria but not viruses?

related to their function?
4. Can I explain that heart rate can be measured by recording the pulse
5. Can I describe how blood pressure measurements record the
pressure of the blood on the walls of the artery?
6. Can I explain why a blood pressure measurement is given as two

value when the heart is relaxed?

Can I explain why high blood pressure increases the risk of heart
16. Can I describe how the misuse of drugs (eg Ecstasy, cannabis,
nicotine and alcohol) can have an adverse effect on health, including
heart rate and blood pressure, increasing the risk of a heart attack?

Can I explain how the kidneys balance water levels by producing
dilute or concentrated urine as a response to concentration of blood
plasma, which is affected by external temperature, exercise level and
intake of fluids and salt?
10. Can I explain how concentration of urine is controlled by a
hormone called ADH, which is released into the bloodstream by
the pituitary gland?
11. Can I explain how ADH secretion is controlled by negative
