PROPER CARE TOLD
TO AVOID DISEASE
0vereating, 0verexercise and
Underexercise Contribute
to ArterioscIeroSiS.

Beware Of overeating, cgerexercise,
or lack of sufficient exercise II you want
to escape dread "arteriosclerosis," bet
ter known as plain hardening OF the
arteries"
This is the warning sounded by the
United States Public Health Service to
modern America, with q simple ex-
PLANTATION of this all-too-common but
generally misunderstood difhculty OF the
human system
Infectious diseases and So-caled focal
infections, such as bad ronsils, injected
teeth or sinuses by their production OF
poisons are believed to be factor in
causing arterioScleroSts.
In its explanation Of hardening OF
the arteries" the Public Health Service
explains that certain things are required
for maintenance Of the human machine.
1t l5 necessary, for instance, that proper
food be taken into the body to provide
material for bodily growth and repair
and to furnish heat and energy for the
body.
System Explained.
It is also necessary that air be taken
into the lungs to provide the oxygen
that is necessary for the utilization OF
these elements. But 1t Is not sufncient
that the food merely be taken into the
stomach and there digested, or that the
air be merely breathed into the lungs.
1t is essential that they be transported
to the remotest parts OF the body for
the nourishment of its mfnutest mem
bers; and for this purpose nature has
devised the blood as medium Of trans
portation, and the circulation system
as a system of distribution.
The circulation Of the blood is &C
complished by four divisions of the
circulation system, namely. the central
Sfo
tributing system, or arteries; the ter
minal fine divisions Of the system
which deliver blood to the tissues,
called capillaries, and the collecting
system, or veins. These parts Of the
circulation system are so 1nterde-
pendent that it Is difficult to discuss
the diseases or injuries Of one without
involving the others. However, this
discussion is most concerned with the
disabilities of the distributing system,
or arteries The arteries are pipe lines
whose walls contain elastic tissue and
some muscular tissue. When the heart
beats the blood Is propelled into the
arteries, and the elasticity OF their walls
makes possible the maintaining OF a
constant blood pressure and the mus
cular elements aid in boosting the
action of the heart and assisting in
the propulsion of the blood. Since the
arteries must accommodate their action
to every change or emergency that con-
fronts the body, they are constantly
subjected to considerable strain. Within
wide limits they are able TO respond
efficiently and without injury, but TN
due strain too long continued or too
often repeated results in weakening
and disease of these vessels. BY far
the most common disease of the ar
teries is arteriosclerosis.
ArterioSclerosiS is condition OF the
arteries in which their elasticity Is lost
and the muscular tissue and the elastic
tissue In their walls is replaced-flrst
with inelastic connective tissue and
later with deposits Of lime. The lining
of the artery becomes roughened and
at times covered in spots by flakes OF
lime deposit When the arteries be-
come thus hardened and inelastic they
no longer properly assist in the circu-
1ation of the blood, but rather retard
it, and thus throw increased work on
the heart. They no longer help to
maintain an even pressure of the
blood and as their caliber, or inside
diameter, is diminished, particularly in
the smaller vessels, they do not de-
liver enough blood for the adequate
nourishment Of the parts. The artery
walls having lost their elasticity have
tendency to become somewhat brittle
and are more liable to rupture on any
increase Of blood pressure or other
strain.
