This is how our amazing human heart works

Science is one of my favorite subjects. In fact, I used to represent our school on my elementary days on various Science pop quizzes. I find it enjoyable to learn diversified facts about human bodies. To share what I learned (from books and facts I gleaned from the net), why not blog them here from time to time. Remember, knowledge is power (who quote this? Francis Bacon? hmmmm).

To start with let's learn some interesting new facts and information about how the amazing human heart works.

1. Every day, your heart beats about 100,000 times, sending 2,000 gallons of blood surging through your body.
2. Although it’s no bigger than your fist, your heart has the mighty job of keeping blood flowing through the 60,000 miles of blood vessels that feed your organs and tissues
3. a man’s heart weighs about 10 ounces, while a woman’s heart weighs approximately 8 ounces
4. When you laugh, the lining of your blood vessel walls relaxes and expands. So have a good giggle. Your heart will thank you.
5. Your heart is located in your chest and is well protected by your rib cage.
6. The study of the human heart and its various disorders is known as cardiology.
7. You’re more likely to have a heart attack on Monday morning than at any other time of the week.
8. You might have felt your own heart beating, this is known as the cardiac cycle. When your heart contracts it makes the chambers smaller and pushes blood into the blood vessels. After your heart relaxes again the chambers get bigger and are filled with blood coming back into the heart.
9. Electricity going through your heart makes the muscle cells contract.
10. You might have watched television shows or movies where a patient in a hospital is attached to an electrocardiogram machine or ecg machine. You might recognize it as the machine with a line moving across a screen that occasionally spikes (or remains flat when a patient is dying). This machine can measure the electricity going through a patient’s heart. A doctor can use the information to know when a patient is having heart rhythm problems or even a heart attack.
11. Heart attacks cause scar tissue to form amongst normal heart tissue, this can lead to further heart problems or even heart failure.
12. Heart disease is the biggest killer of both men and women. And both genders should heed this healthy advice: Don’t smoke, keep your blood pressure and cholesterol levels in check, and watch for the obvious and the more subtle warning signs your heart could be in trouble.
