facts about human heart

Heart – A very important organ

The heart is important because it pumps blood around your body, delivering oxygen and nutrients to your cells and removing waste products. The heart has four chambers: two upper chambers called the right and left atria (singular: atrium) and two lower chambers called the right and left ventricles.

Men’s Heart rate is less than women

The average adult male heart rate is between 70 and 72 beats per minute, while the average for adult women is between 78 and 82 beats. This difference is largely accounted for by the size of the heart, which is typically smaller in females than males.

Heart diseases and death rate

Heart disease is the leading cause of death for men, women, and people of most racial and ethnic groups in the United States. One person dies every 36 seconds in the United States from cardiovascular disease. About 655,000 Americans die from heart disease each year—that’s 1 in every 4 deaths.

Size of our heart

The heart weighs between 7 and 15 ounces (200 to 425 grams) and is a little larger than the size of your fist. By the end of a long life, a person’s heart may have beat (expanded and contracted) more than 3.5 billion times.

Causes of Heart Attack

A heart attack occurs when one or more of your coronary arteries becomes blocked. Over time, a buildup of fatty deposits, including cholesterol, form substances called plaques, which can narrow the arteries (atherosclerosis). This condition, called coronary artery disease, causes most heart attacks.

Laughing is good for heart

Endorphins promote an overall sense of well-being and can even temporarily relieve pain. Laughter protects the heart. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems.

How to avoid heart attack ?

Fortunately, there are many things you can do to reduce your chances of getting heart disease:

1. Control your blood pressure.
2. Keep your cholesterol and triglyceride levels under control.
3. Stay at a healthy weight.
4. Eat a healthy diet.
5. Get regular exercise.
6. Limit alcohol.
7. Don’t smoke.
8. Manage stress.

Can we cure heart attack ?

Although we can’t cure heart disease, we can make it better. Most forms of heart disease are very treatable today. There is some evidence that normalizing high blood pressure and lowering cholesterol to very low levels will partially reverse plaques in the coronary arteries.
