blood pressure water flows with a higher
pressure when you connect a tube to a
pump set operating in your field or
house also the tubes first open if the
pressure is very high similarly when the
heart pumps blood into systemic a Horta
or into the pulmonary trunk the blood
flows with pressure in the blood vessels
the pressure with which the blood flows
in the blood vessels is called the blood
pressure usually called BP arteries
receive blood from the heart so blood
pressure is higher in the arteries the
blood pressure gradually decreases as
blood flows into capillaries when this
blood is collected into veins blood
pressure is greatly reduced so blood
pressure is less in the veins when
compared to the arteries blood pressure
is measured by doctors using an
instrument called a sphygmomanometer
blood pressure levels are written in the
form of 120 by 80 this is normal blood
pressure the numerator 120 represents
systolic pressure and the denominator 80
represents diastolic pressure during the
systolic when the ventricles contract
the blood is pumped into the arteries so
the blood pressure in the arteries
increases immediately after the systolic
this rise and the blood pressure in the
arteries is called the systolic pressure
when the diastolic occurs more blood is
pumped by the heart the blood vessels
return to the normal diameter and
maintain blood pressure at a lower level
this is diastolic pressure hypertension
or high blood pressure in some people
the blood pressure will be very hot more
than the usual 120 by 80 such a
condition is called hypertension usually
called high BP one of the reason
for this is the blocking of arteries by
cholesterol constant stress and strain
for a long time
improper functioning of kidneys smoking
and alcohol consumption are also the
reasons for hypertension this condition
if not treated for a long time may also
lead to other health problems and it may
lead to the death of the person diet
control moderate exercise and avoiding
stress smoking and alcohol consumption
as well as taking appropriate medicines
will help to control this problem
