WHAT IS HUMAN BODY

The human body is a fascinating and complex living thing. Throughout our life, the body performs a lot of tasks, often without our conscious control. Every day our heart beats about 100,000 times, and we do not even have to think about it! After we have completed the act of chewing and swallowing food the rest of our digestive system swings into action to extract the nutrients, and again we do not have to concentrate on doing it.

The human body starts life as single cell – an egg, produced by a female, fertilized by a single sperm, produced by a male. From this simple beginning all the variety of tissues and organ systems that make up our body develop: skeleton; muscles and nine systems, which work harmoniously together in a healthy body. They are: respiratory system – the windpipe, lungs and diaphragm; circulatory system – the heart, blood and blood vessels; digestive system – the stomach, intestines, pancreas and liver; nervous system – the brain, spinal cord and nerves; the skeletal and muscular systems; excretory system; endocrine system; the reproductive system, that starts the whole process off again and the senses – eyes, ears, tongue, nose and skin.

It is quite clear, that such a complex construction is bound to go wrong from time to time and very few of us can claim to be in perfect health. However, the healthier we are the better our body will be able to function. And there is always something we can do to improve matters. A good diet is a must as – poor nutrition invariably leads to poor health. Raising our overall level of fitness by taking regular exercise will improve our ability to fight of any illness. At the same time it is also important to get sufficient rest since it is during these quiet periods that the body carries its running repairs. Too much alcohol will damage the liver, a vitally important organ that we cannot live without. And smoking, with the cocktail of carcinogens in cigarette smoke, is a bad idea at any time.

Such an amazing thing as human body deserves to be respected and looked after. If nothing else, it is the only one well have, it has to last us a lifetime and, and when it goes, we go too!
