6. Many attempts have been made to dissolve gall stones by medical treatment to
avoid an operation.
7. Food is broken down by physical and chemical means into forms in which it can
pass through the walls of the alimentary canal into the blood to be transported
around the body.
8. The early Greeks were the first Western men to speculate on the origin of the
universe and of the earth and its inhabitants.
9. Insulin injections are regularly used to treat diabetes mellitus, but care has to be
taken not to exceed the dose as this will cause hyperinsulinism.
10. To guard against rapid depletion of the short-lived neutrophils, the bone
marrow holds a large number of them in reserve to be mobilized in response to
inflammation or infection.
11. The recognition of Rh factor and its importance in haemolytic anaemia of the
newborn was an important development, chiefly because to be forewarned is to
be forearmed.
12. The anesthesiologist selects the drugs to be used, decides how they are to be
administered and constantly monitors the patient condition during the operation.
13. Vitamin B12 deficiency is nearly always due to failure to absorb the vitamin. To be
absorbed it has first to be combined with intrinsic factor, a protein formed in the
stomach.
14. Paracelsus [, paera'selsas] (1493 — 1591) seems to have been the first physician to
recognize a trade as the cause of a disease.
15. Lack of sufficient calcium causes the nervous system to become more and more
excitable, and the nerve fibers begin to fire spontaneously.
16. Although hundreds of chemicals have been reported to produce cancers in experi
mental animals, only about two dozen have been verified as causes of cancer in
man.
17. In order to contract when it is stimulated, a muscle fibre must have an adequate
supply of blood to provide sufficient oxygen and nutritional materials and to

1. The early physicians who used remedies taken from plants to treat their patients
were probably the first people to study plants with care and keep a record of their
observations. These physicians had to tell poisonous, medicinal, and useless plants
from each other in order to treat their patients.
2. Early records indicate that illness was generally thought to be caused by unseen
demons or evil spirits that entered the body where it was most vulnerable. Today,
in much the same fashion, disease is said to be caused by creatures invisible to
the naked eye that enter the body.
3. In ancient Greece surgeons were recognized as subordinate medical practitioners.
Physicians were believed to be men of learning, employing their intellect to
diagnose the causes of diseases. Surgeons by contrast used their hands, not their
heads, and the fact that their work involved the shedding of blood allowed them
to be linkened disdainfully to butchers.
4. To remove the disease germs and the undesired sediments water which comes
from lakes or rivers or even from some wells must be purified for human use.
Enough chlorine is put into the water to kill any disease germs present but not
enough to injure people or animals. Sometimes both filtration and chlorination
are used to assure a supply of pure water.
5. Strong emotions like anger cause physical changes to take place in the body.
The heart beats faster, the stomach tightens, and a person may perspire. If you do
not do something to deal with the emotions, the body does not relax. It stays in
this state of tension. Over a period of time fatigue can set in and physical illness
may even develop. It is unhealthy to keep feelings inside, for you put an additional
strain on your body.
6. Cigarette smoke has been shown to contain numerous compounds that are known
to cause cancer in experimental animals and that appear to be strongly linked to
human cancer. Cigarette smoke also has been shown to contain a number of
cocarcinogens, substances that appear to enhance the effect of carcinogens when
they are administered concomitantly. Smoking has been proven by scientific
research to be detrimental, or harmful, to health.
7. To survive, an organism must be capable of responding to changes in the environ
ment. To respond quickly and appropriately, its parts must be in communication
with the outside world and with one another. This is true of small unicellular
organisms and of large multicellular ones. A large multicellular organism, with its
low ratio of surface area to volume, requires a special system to transmit information
inward and to effect coordinated responses to the information. The nervous system
fills this need.
8. A patient about to undergo surgery is instructed not to eat or drink anything for
several hours prior to the operation in order to make it easier for the surgeon to
operate and to avoid complications from the anesthetic. A patient is often given
an enema just before the operation to void the colon of waste material. Sometimes
a urinary catheter is used to drain the bladder. The area to be operated on is
shaved and scrubbed with soap, and an antiseptic is applied to avoid infection.
9. Efforts to understand the metabolic and dietary factors that lead to osteoporosis,
or loss of skeletal mass with aging, emphasize the importance of calcium
bioavailability. Calcium in food exists mainly as complexes with other factors
from which the calcium must be released to be absorbed. Plant constituents of
the diet, in particular, may reduce calcium bioavailability so that people who do
not use dairy products are less likely to obtain adequate amounts of calcium.
10. There are hundreds of different alternative therapies used by millions of people
worldwide to treat every ill imaginable. People are turning to alternative therapies
because virtually every drug has been shown to have some side effects and
many patients have become dissatisfied with the inability of conven
tional treatments to cure certain conditions — particularly chronic diseases such
as arthritis. The common feature that seems to run through every one of the
alternative treatments is the importance placed on the whole person, not just on
specific symptoms — this is known as the holistic approach.
11. Each day, about 0.8 per cent of the body's red blood cells wears out and is
destroyed. If the body fails to replace these cells at the same rate, anaemia
results. It is considered to exist if hemoglobin levels are below 13 grams per 100
ml in males and below 12 grams per 100 ml in adult nonpregnant woman. If the
blood is examined under a microscope the red cells are seen to be paler and
smaller than normal. Anaemia is not a disease itself, but a condition caused by a
variety of diseases and disorders. In many cases the anaemia is found to be due
to a combination of two or more causes.
12. Lavoisier was a brilliant chemist and the first to show the significance of the
respiratory process in relation to food. He made the first quantitative measurements
of the metabolism of man and his studies were the first to show that respira
tion was a process of the slow combustion of carbon and hydrogen within the
body — oxygen being consumed to support the combustion and carbon dioxide
being produced as a result. It took over a hundred years with further advances in
the sciences of chemistry, physics, and physiology before nutrition as such was
recognized as a new science.

1. The movement of molecules or ions from a region of higher concentration to a
region of lower concentration is called diffusion. Molecules that are moving from
a region of higher concentration to a region of lower concentration are said to be
moving along a diffusion gradient, while molecules going in the opposite direction
are said to be going against a diffusion gradient. When the molecules, through
their random movement in all directions, have become distributed throughout
the space available, they are considered to be in a state of equilibrium. The rate
of diffusion depends on several factors, including temperature and the density of
the medium through which it is taking place.
2. A muscular fibre may be said to consist of a soft contractile substance enclosed in
a tubular sheath, named sarcolemma. Upon examination of a voluntary muscular
fibre by transmitted light, it is found to be apparently marked by alternate light
and dark bands, which are nearly of equal breadth. If the surface is carefully
focussed, rows of granules will be detected at the point of junction of the dark
and light bands. By treating the specimen with certain reagents fine lines may be
seen running transversely between the granules uniting them together. This
appearance is believed to be due to a reticulum or network of interstitial substance
lying between the contractile portions of the muscle.
3. Emphysema is a condition in which the lining of the air sacs in the lung loses its
elasticity and is unable to expand, which means that the lungs cannot provide
enough oxygen to the body. The person most likely to develop emphysema is a
man older than 45 who is a heavy smoker, but this gender difference is likely to
disappear as more women continue to smoke for longer periods of time. In
experiments with laboratory animals, ozone and nitrous oxide — chemicals that
occur in the grey-blue exhaust from motor vehicles and are present in polluted
air — have been shown to cause changes in lung tissue similar to those seen in
people with emphysema. Not surprisingly, emphysema is more common in large
cities and highly industrialized areas.
4. When scientists first examined the human brain, they found it to be divided into
two halves, or hemispheres, which are nearly identical in appearance, mirroring
each other just as the two sides of the body do. It was found that the two sides of
the brain have different functions. Many investigators have studied the differences
between the functions of the two hemispheres and found their relationship to be
quite complex. The left brain is supposed to be logical, rational, analytical, whereas
the right brain is supposed to be creative and emotional. Interestingly, the fibres
which join the two halves of the brain have been found to be larger in women
than in men. Nerve cells in the brain use electrical signals, but in addition they
communicate chemically with neurotransmitters. No one knows how many
neurotransmitters there are, but extensive efforts to identify the chemicals and
map the neurons producing them are currently under way. The first agents to be
identified as neurotransmitters were all small molecules, single amino acids or
their derivations or such simple compounds as acetylcholine.
