To be able to get the muscles to function
efficiently they might need energy in the type of glucose therefore the
liver secretes a few of its store of blood sugar which is transported
to the muscular tissues inside the blood stream. Oxygen is also
required in order to transform the glucose directly into energy so this
is also transported through the blood. Therefore, one's heart needs to
pump harder to obtain the blood where it's most necessary and blood
pressure level rises because of this.
Effects Of Tension Stress
There is a limit to the amount of blood
available in the body so it has to be diverted from somewhere else for
the time being. Digestion slows down or is halted; the salivary glands
dry up; the stomach and intestines stop working and the sphincter
muscles close to avoid defecation and urination taking place (sometimes
the parasympathetic nervous system over-reacts and the opposite occurs
with 'wetting your pants with fright' and diarrhea). The blood vessels
in the kidneys constrict. The are more effects of tension
as below:
-
For the reason that lungs will need to
take in more air to produce oxygen and should also eliminate more co2,
inhaling and exhaling must become more quickly, much deeper or
gasping..
-
The skin changes under stress. Due to
one's body tends to obtain too hot in vigorous actions, the skin works
on for cooling by perspiring, as well as the electrical resistance of
the skin is decreased. To make sure that a few of the blood could
possibly be provided to muscles the capillary bloodstream shrink in
which we could look pale due to this fact. The skin also has to excrete
more of the body's waste products.
-
There is a change in the chemical
composition of the blood with more salt and less potassium. The
pupils of the eyes dilate.
All these, and many other complex changes
occur, some of them in a split second. When physical action has
been taken and the danger is over, the bio-chemicals of stress used up
as intended, everything settles down to normal, relaxation takes place
and no harm is done. The body has adapted to normal stress and
equilibrium is once more established.
