Human Heart - Amazing and interesting facts
1. The human heart is no bigger than a fist
and yet is wrapped in so much muscle that it can continue pumping even if a third of its
muscle mass is destroyed.
2. Human heart beat 35 million times a year.
3. The heart beats about 100,000 times each day.
4. It is amazing but true that In a 70th year lifetime, the average human heart beats more
than 2.5 billion times.
5. The adult heart pumps about 5 quarts of blood each minute it is approx. 2,000 ( 9120 liters ) gallons
of blood each day, throughout the body.
6. The heart pumps about one million barrels of blood during an average lifetime - that\'s enough
to fill more than 3 super tankers.
7. Your system of blood vessels - arteries, veins and capillaries - is over 60.000 ( 96.000 km ) miles long.
That\'s long enough to go around the world more than twice!
8. Believe it or not but 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.
9. An adult woman\'s heart weighs about 8 ounces and a man\'s about 10 ounces.
10. An adult\'s heart is about the size of two fists and a child\'s heart is about the size of a clenched fist.
11. Do you know that Blood is about 78 percent water.
12. Blood takes about 20 seconds to Circulate throughout the entire vascular system.
13. Raymond Viessens, a French anatomy professor, first described the structure of the heart in 1706.
14. The Electrocardiograph (ECG), used to evaluate the heart\'s rate and rhythm,
was invented in 1902 by Willem Einthoven, A Dutch Physiologist.
15. The human heart weighs less than a pound.
16. The first heart specialists emerged after World War I.
17. Most heart attacks occur between the hours of 8 and 9 AM.
18. The human heart can create enough pressure that it could squirt blood at a distance of thirty feet.
19. The aorta, the largest artery in the body, is almost the diameter of a garden hose. Capillaries, on the other
hand, are so small that it takes ten of them to equal the thickness of a human hair.
20. Your body has about 5.6 liters (6 quarts) of blood. This 5.6 liters of blood circulates through the body three times every
minute. In one day, the blood travels a total of 19,000 km (12,000 miles), that\'s four times the distance across the US from
coast to coast.
21. Every day 2,700 people die of heart disease.
22. Feel your pulse by placing two fingers at pulse points on your neck or wrists. The pulse you feel is the blood stopping and
starting as it moves through your arteries.

24. Give a tennis ball a good, hard squeeze. You are using about the same amount of force your heart uses to pump blood out to the body. Even at rest, the muscles of the heart work hard--twice as hard as the leg muscles of a person sprinting.
25. Oxygen-poor blood flows from the body into the right atrium.
26. Hold your hand out and make a fist. If you are a kid, your heart is about the same size as your fist, and if you are an adult,

31. In 2010, heart disease will cost the United States $316.4 billion. This total includes the cost of health care services,
medications, and lost productivity.
32. In a 2005 survey in USA, most respondents-92%- recognized chest pain as a symptom of a heart attack. Only 27% were aware of all major symptoms and knew to call 9-1-1 when someone was having a heart attack.
33. About 47% of sudden cardiac deaths occur outside a hospital. This suggests that many people with heart disease don\'t act
on early warning signs.
