Heart:Most Important Organ

Heart being the most important organ of our body needs proper care. Heart when it stop beating life will also end. So, that is why we should need to take care of our heart and not to abuse it. Let your heart stay healthy in order to have a long life.

The heart is a myogenic muscular organ found in all animals with a circulatory system (ncluding all vertebrates), hat is responsible for pumping blood throughout the blood vessels nby repeated, rhythmic contractions. The term cardiac (as in cardiology) means “related to the heart” and comes from the Greek, kardia, for the “heart”.

There are so many different forms of heart diseases and this is the number 1 killer not only in the US but throughout the whole world. The most common cause of heart disease is narrowing or blockage of the narrow arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and happens slowly over time. It's the major reason people have heart attacks.

Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure. Some people are born with heart disease.

Causes of heart disease:
High Blood Cholesterol. One of the major risk factors for heart disease is high blood cholesterol. Cholesterol, a fat-like substance carried in your blood, is found in all of your body's cells. Your liver produces all of the cholesterol your body needs to form cell membranes and to make certain hormones. Extra cholesterol enters your body when you eat foods that come from animals (meats, eggs, and dairy products).
Although we often blame the cholesterol found in foods that we eat for raising blood cholesterol, the main culprit is the saturated fat in food. (Be sure to read nutrition labels carefully, because even though a food does not contain cholesterol it may still have large amounts of saturated fat.) Foods rich in saturated fat include butter fat in milk products, fat from red meat, and tropical oils such as coconut oil.
Too much low-density lipoprotein (LDL or "bad cholesterol") in the blood causes plaque to form on artery walls, which starts a disease process called atherosclerosis. When plaque builds up in the coronary arteries that supply blood to the heart, you are at greater risk of having a heart attack.

Obesity and Overweight. Exra weight is thought to lead to increased total cholesterol levels, high blood pressure, and an incrreased risk of coronary artery disease. Obesity increrases your chances of developing other risk factors for heart disease, especially high blood pressure, high blood cholesterol, and diabetes.
