Heart is important to function all our organs in the body. The heart continue beating all his life day and night. If at rest, it beats slowly and quietly. To response to an emergency, the heart will beats fast transporting blood to whatever portion of the body that needed most.
It is an efficient muscular pump dependent on the condition of the fibers in its muscular walls. Once the fibers is damage, it will produce a striking changes in its circulation throughout the whole body.
A healthy person need 5 liters of blood, keeping its circulation by the motion of the heart. He is not strain by overwork. It can only be damage due to disease. Too much activity is not recommended to a damaged heart to avoid straining it beyond its limit.
Everyone should avoid being overweight and no sufficient exercise to protect the heart. It weakens the body and hamper the normal circulation of the blood. The arteries will harden and the elastic tissue in the walls no longer flexible. This may raise the blood pressure and increase the work of the heart.
As long as we are alive, the heart never stop working. It has reserve power to meet any crisis that may arise. If damaged by disease, it has the ability to repair itself.
After a vigorous contraction, the heart relaxes and momentarily rest. The elastic walls of the arteries expand and the volume of blood passes through it on its way to the smallest vessel.
To keep the blood in circulation, it pump under certain amount of pressure to reach the brain.
That’s the wonder of being a HEART.
