The Hormone System
" And if you would count Allah(God)'s favors, you will not be able to number them; most surely Allah(God) is Forgiving, Merciful." ( Quran : 16/18 )
Your hundred trillion cells work together in great harmony, just as if they were aware of one another. This harmony can be seen in the number of times your heart beats as you read these words, the level of calcium stored in your bones, your blood-sugar level, the amount of blood filtered by your kidneys every minute - in these, and thousands of other similar details.
Bearing all these systems in mind, you might compare the human body to a giant orchestra consisting of 100 trillion musicians, playing the most incomparable compositions 24 hours a day. The tempo sometimes speeds up, or slows down; sometimes with a fast tempo, and at others with a calmer melody. However, the musicians in the orchestra never fall out of tune with one another. So Who is it who conducts this matchless orchestra? How can millions of different musicians are able to play their common notes at the same time, with different instruments?
Hormones are proteins charged with carrying messages between the 100 trillion cells in the human body cells. Consider, for example, the secretin that starts being secreted during food digestion. Though you may be quite unaware of this hormone, it prevents your stomach from being harmed by acid. It's impossible for you to prevent this or to protect yourself by any other means. And this applies to all the other organs, enzymes and systems in your body.
A perfect system in all aspects has been established in the human body, although people are unaware of what is taking place within them. Substances in your body issue instructions on your behalf and maintain your body's equilibrium, directing you to eat or drink or move more quickly, even while you are unaware of these directions. Your body's survival depends on a chain of command controlled by means of hormones.
Airplanes, spacecraft and even modern automobiles all now feature computers that monitor the vehicle's status and capacity. Thousands of years before human beings developed these systems, however, perfect control systems were already in operation, inside the human body itself.
The body's control and supervision mechanisms - the nervous system that stretches along an organic network, and the hormonal system that analyzes chemical signals - possess a technology far higher than any human can imagine.
To a large extent, both systems work according to classical reaction principles. A message sent from the control system causes the target organ to increase or reduce its activity. Analysis is performed at every moment, thanks to a constant flow of information, and new instructions are issued according to that analysis. Millions of pieces of information are processed every second. The nervous system permits information exchange by means of nerves that span the entire body.
The details of this system, one of the proofs of Allah(God)'s existence and infinite might, again encourage us to consider His creation. In verses, Allah(God) commands people to think about the entities He has created, and to turn to Him:
" He it is Who sends down water from the cloud for you; it gives drink, and by it (grow) the trees upon which you pasture. He causes to grow for you thereby herbage, and the olives, and the palm trees, and the grapes, and of all the fruits; most surely there is a sign in this for a people who reflect. And He has made subservient for you the night and the day and the sun and the moon, and the stars are made subservient by His commandment; most surely there are signs in this for a people who ponder; And what He has created in the earth of varied hues most surely there is a sign in this for a people who are mindful." (Quran: 16 / 10-13)
