Learn how heart attack occurs

We all know that the main job of our heart is to pump blood. It is like a water pump whose job is to pump water to various tanks. But like the pipe of the water pump, our heart pipes (arteries) also can get clogged, causing problem in the flow of blood to the body. Knowing your heart and how it functions will help you take care and avoid such problem. More than 2,000 Americans die of heart disease every day. The good part is new techniques and advancement in medical science has helped many people survive from this ailment. 

 Architecture of your Heart.

 The heart has four partitions

 1. Right Atrium (RA).

2. Right Ventricle (RV).

3. Left Atrium (LA).

4. Left Ventricle (LV).

 Each partition has a one way valve which lets blood flow in one direction only. What the heart beats (systole), the blood is pushed out of the heart. Then the heart pulls blood in (diastole). This action continues throughout  your life cycle. The right side of the heart pumps blood to the lungs where oxygen is collected passed back to the heart and this is then circulated throughout the body. This process helps to supply oxygen to all the parts of the body.

 Pulse Rate

 Pulse rate is calculated per minutes and will vary from age to age.

 Infant              130

1 years            120

3 years            100

6 years             100

8 years              90

12 years           85

Adult                 60 to 100

 Hearts Electric system.

 Would you want to know how the heart beats? How does it manages to beat every second, minute and day after day?

 It’s because of a special type of cells that are capable of generating electric pulse on their own. These cells spread all over the heart which produces electric signals in the pacemaker cells of the heart. This helps the heart to contract. These electric cells are responsible to create the right rhythm so that your heart pumps blood in a synchronized way. This pacemaker is called Sinatral node (SA node). Its located in the RA. In some patients these cells are damaged or not able to function. An artificial pacemaker is fitted in the body to perform this task.

 An average heart pumps 7,200 liters of blood per day.  Do your calculation as to how much it work out for a year and lifetime. You will be amazed with the number.
