If we accidentally cut our arm, several small blood vessels are cut apart.  In order to control the flow of blood from this vessels,   the physician has to control the bleeding by repairing the damaged nerve tissue by suturing it. Further, the doctor will apply disinfectant to avoid infection. Any infection to the damaged skin affects the ability to heal naturally. Redness and swelling are dangerous it leads to a more serious one, gangrene. That was the reason why any cut in the skin even how small it is should  be taken care of immediately.

It is a threat to anyone having diabetes that ends up with lost arms and legs. Taking antibiotics is one way of protecting infection. Constant dressing is necessary every day.  With the application of disinfectant it ensures the skin is clean and will starts healing.

The question is, how does it heal? It is a miracle in nature. The nerve fibers above the cut will begin to grow in its own time. Under some mysterious circumstances, each of the severed fibers started connecting again.

The body cells will continue and busy repairing the damaged skin and the tiny fibers will carefully thread their way to reach the spot of injury.

Our body has the ability to response to emergency. The cells will react to any disturbances to the skin and do whatever necessary to repair itself.

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.
