Star is a ball of hot gasses that shines permanently in the sky. Through our naked eyes, they seem to twinkle as we see them but actually they do not. The sun proves that stars do not really twinkle because sun is the nearest star on earth. It never happens that the sun twinkles as it shines during the day.

The Human Body is very complex. It involves numerous organs working closely together to carry out a specific task. This functional association of organs are called organ systems or, in some references, body systems or biological systems. The main function of the organ systems is to maintain the homeostatic environment or internal condition of the human body. Thus, making humans work with great efficiency and flexibility. Disruption of this internal balance may lead to certain diseases, complications, and worst, even death.

In this article, I will discuss the different organ systems and their role in maintaining the internal balance of the human body.

... People are delighted when they find out through science the basis of some natural phenomenon. Who would not be, especially nowadays that tremendous technical advances have been brought by science and thus scientist has acquired immense prestige.

Computers made possible round-trips to the moon and a host of applications in all aspects of modern life. Imagine the amazement and wonder of one of our ancestors brought back to life as he or she surveys all the tools provided for man’s well-being by modern technology. Night is banished by electric lights, distant events are brought into home by TV via satellites, food is preserved fresh in an electric refrigerator and quickly prepared in a microwave oven, travel to Paris for a shopping tour is made possible by supersonic jet, and so forth and so on ...
