Whether we like it or not, our body needs calcium. There are many beneficial effects in taking calcium as mineral. It builds and maintains good bones and teeth and in blood clotting. It was needed in the transmission of nerve impulses. It is helpful in the regulation of the heart rhythm. Calcium is a living tissue constantly broken down and in build up process. If you are healthy and have enough calcium and exercise, your bone production will increase.

A disease that we should be aware of is osteoporosis. If the bones weakens, it causes an imbalance. He losses bones as he aged. Taking an adequate intake of calcium provides an important source of avoiding bone loss in later life.

How can we slow it down? Get enough exercise. Take vitamin D an important source you can get from the sun aside from calcium supplement. A green-leafy vegetables is also rich in vitamin K. In order to lower the risk of osteoporosis, avoid taking caffeine as it increases the risk of fracture. Instead of going in, calcium was excreted in urine out of the body. Avoid too much protein as it cause calcium to go out from the bones especially animal protein.

A lifelong intake of dietary calcium is necessary. It helps slow bone loss. At moderate level, taking calcium has benefits in lowering the risk of hypertension. Sources of calcium can be found in dairy products, spinach, baked beans, oranges, green peas, and many others. Calcium is an element that has many benefits. It helps the bones to function effectively.

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.
