of the human heart in cross section.
is the body's power house, a muscle that has regular, rhythmic
contractions that keep blood pumping 24/7 throughout the body's
keeps the beat about 72 times per minute as it pumps
2,000 gallons of blood a day to thousands of miles of large
arteries, smaller veins and tiny capillaries.
How the heart works
Just like an electric pump, your heart works using its
own electrical system to contract the heart's walls.
on-off contractions are what keeps the body's "juices"
flowing, with the heart's inlet and outlet valves ensuring
that blood flows in the right direction to and from all areas
of your body.
if high blood pressure or other conditions result in a weakened heart,
your bodys organs wont receive enough nutrients
to function normally and thereby trigger more harm.
Have a heart - keep it healthy
the heart is so vital, keeping it strong and working properly
is probably the best thing we can do for our overall health,
especially as we age
In the Western world heart
disease has reached epidemic proportions, but with a
few simple changes the chances of heart damage can be drastically
Obesity, high cholesterol, and high blood pressure are all
major risk factors for the many heart related illnesses that
exist. Fortunately for us, there are two simple things we
can all do to thwart all three of these risk factors:
first one is diet
and nutrition, a huge contributor to poor heart health
among a whole host of other related health problems. A good
rule of thumb for all of us to follow is to not eat things
out of boxes, and to eat less meat and carbs, and to eat
more fruits and vegetables. Following this simple rule will
go a long way towards a healthier heart.
other simple thing we can all do to keep our hearts healthy
is to exercise, every
day. Whatever activity it is that you prefer to do, get
out and try to do it at least once a day and it doesn't
have to be sports or jogging.
Even walking qualifies as an excellent way to keep the heart
rate elevated and the heart muscle in optimum condition.
