Heart Facts you would like to know
1. Your system of blood vessels -- arteries,
veins and capillaries -- is over 60,000 miles
long. That's long enough to go around the
world more than twice!
2. When attempting to locate their heart,
most people place their hand on their left
chest. Actually, your heart is located in the
center of your chest between your lungs.
The bottom of the heart is tipped to the
left, so you feel more of your heart on your
left side of your chest.
3. Heart has its own electrical impulse, it
can
continue to beat even when separated
from the body, as long as it has an
adequate supply of oxygen.
4. The “thump-thump”, “lubb-dubb” of a
heartbeat is the sound made by the four
valves of the heart closing.
5. The heart begins beating at four weeks
after conception and does not stop until
death
6. The heart does the most physical work of
any muscle during a lifetime. The power
output of the heart ranges from 1-5 watts.
While the quadriceps can produce 100
watts for a few minutes, an output of one
watt for 80 years is equal to 2.5 gigajoules
7. The heart beats about 100,000 times
each
day. 35 million times in a year and in a 70-
year lifetime, the average human heart
beats more than 2.5 billion times
8. As a kid your heart rate (number of
times
the heart beats in a minute) ranges
between 90-120. As you become an adult
heart beat ranges between 60-72 beats a
minute. The heart rate should be
calculated at resting stage (when you are
relaxed and taking rest).
9. A small mass of specialized muscle on
the back wall of the right atrium called
the sino-atrial(SA) node, also known as
the pacemaker sends out electrical
impulses to generate the heartbeat at
regular intervals. This is the one that
regulates your heart beat.
10. Every day, the heart creates enough
energy
to drive a truck 20 miles. In a lifetime, that
is equivalent to driving to the moon and
back
11. An adult woman's heart weighs about 8
ounces, a man's about 10 ounces
12. A child's heart is about the size of a
clenched fist; an adult's heart is about the
size of two fists.
13. Blood is about 78 percent water.
14. Aorta is the largest artery in the body
which helps carries the blood from the
heart to various organs in the body.
15. The heart pumps oxygenated blood
through
the aorta (the largest artery) at about 1
mile (1.6 km) per hour. By the time blood
reaches the capillaries, it is moving at
around 43 inches (109 cm) per hour
16. Blood flows through the heart in this
order: right atrium, right ventricle,
pulmonary circuit, left atrium, left
ventricle and into aorta that delivers
blood to various organs in the body
17. Blood takes about 20 seconds to
circulate
throughout the entire vascular system.
18. Drugs such as cocaine, marijuana can
affects the heart’s electrical activity and
causes spasm of the arteries, which can
lead to a heart attack or stroke, even in
healthy people.
19. Some heavy snorers may have a
condition
called obtrusive sleep apnea (OSA), which
can negatively affect the heart
20. Your body has on an average 5.6 litres
of
blood. 5.6 litres of blood circulates through
the body 3 times every minute. In one day
blood travels around 12,000 miles every
day.
