cardiovascular disease, the application of transplants & issues
Doc Brown's biology exam revision study notes
There are various sections to work through.
Sub-index of notes on non-communicable diseases
(7) alcohol heart transplants
(7a) Alcohol - dangers and issues
(7b) Know about the dangers of solvents
Organic solvents (NOT water) are extremely useful liquids
for preparing solutions in the chemical industry and in many domestic
products in the home including aerosols, glues, paints and cosmetic
They are classified as drugs because they affect the brain
and central nervous system e.g. they cause intoxication effects including
hallucinations (illusions of the mind)
Therefore solvents cause severe and negative effects on
behaviour and character.
The lipids and proteins in the skin are affected and
reducing the ability of skin to protect itself - you can get dermatitis,
sores and lesions and other skin disorders.
Solvents can cause even more serious damage to the nervous
system including the brain, liver, kidney and lungs.
(7c) Cardiovascular disease (CVD)
I've described and discussed CVD on other pages, see links
So I've just added a note on the use of the drug statins.
You should be aware of the use of statins in
lowering the risk of heart and circulatory diseases.
Statins are prescribed drugs
that help reduce cholesterol levels and research trials have shown they can
have a significant effect in diabetic patients.
The statins drug trials were
done using a large sample of people and half were given the drug and half
Nobody knew who had the drug,
half were given statins, but the other half, the control group, had a
placebo - a substance containing NO medication.
Several independent studies like
this 'blind trial' have shown that people treated with statins had reduced
The human circulatory system - including the causes
and treatment of cardiovascular disease

(7d) The use of organ transplants
Keywords, phrases and learning objectives for this part on dangers of alcohol,
solvents, CVD and use of transplants
Be able to describe the need for, and use of, the
application of transplants
Appreciate the are concerns and issues about heart
transplants and liver transplant and need for suitable organ donors.
In terms of non-communicable diseases, be aware of
the effects and dangers of drinking alcoholic beverages or wine and
using solvents for recreational purposes.
Be able to describe resulting problems e.g.
addiction, cirrhosis of the live, brain damage and cardiovascular
