The functions of the heart.. Blood flow received from the members of the body and pushing it to the lungs for breathing purified by

The heart is that member muscular vital small in size grip is located behind the sternum and mediates chest but tends to the left side a little bit and has a heart on four booths and a number of heart valves which ensure blood flow received from the members of the different body to pay to the lungs to purified by breathing and then to extract oxygen From the air we breathe to compensate for blood he had lost oxygen, which is essential for operations various vital, and after saturation of blood oxygen and purified within the lungs returns blood to the heart to be pumped to the various organs of the body and the heart pumps about five liters of blood rich oxygen and food every minute of all the members and the body's cells But the heart of its feeding vessels and Come through the coronary arteries that come out of the coronary artery (aorta), which is the main port of the flow of blood from the left ventricle. There Harianan Tajian (left and right) go out just above the aortic valve spreads Alharianan and their branches over the outer surface of the heart and graduated two smaller branches to implement within the heart muscle fed oxidized pure blood. 

The process control in the process of contraction and energizes this strange pump is up regularly through the mechanism of electric complex can be recorded by ECG from above the surface of the human body. 

Or figure normal heart rate ranges from 60-100 beats per minute rate of 70 beats per minute or 4200 accuracy in time or 100,800 accuracy day or 37,000,000 inaccuracies in the year. 

The heart pumps about 70 ml of blood each time or 5 liters per minute or 300 liters per hour or 7,200 liters per day or 216000 liters every month or 2,592,000 liters per year. The heart can pump about 35 liters per minute during the effort muscular and athletic. 

The form of God Almighty this muscle that is essential to us by so renewed cells and tissues throughout the years to become one able to meet the demands of life at all ages Valkhmul and lack of movement, obesity and lack of exercise as well as smoking, high blood pressure and diabetes and emotions neurological and psychiatric that will transform muscle to pump weak or infect the muscle nerves affect heart function So Fa sports and movement and to refrain from smoking and avoid obesity and the treatment of the aforementioned diseases will strengthen the heart and maintain its functions and vitality.
