Consider the smells of new-baked bread, honeysuckle in the garden, new-mown grass, rain-washed soil, meat cooked to perfection, fresh- picked strawberries, peaches and parsley, the soap you use, your fragrant shampoo and so many more: For all of these, you are indebted to the sensitive structure in your nose.

Few people ever consider the many smells they encounter during the course of the day, nor how these are shaped by the organs within their heads. Yet your sense of smell imparts the flavors to what you eat. Smell is one of the senses that let you identify objects.

Smells enter through the nose with every breath you take. The human nose possesses the impressive ability to analyze a scent in 30 seconds and to distinguish between some 3,000 different chemicals.

In the upper part of the nose, two small areas known as the olfactory epithelia contain a large number of nerve cells. These areas are responsible for scent perception. Scents move as molecules in the air. As you breathe, these molecules enter the nose alongside oxygen. When the scent molecules carried by the air reach the olfactory epithelium, the receptor cells there are stimulated and send an electrical signal to the brain. The brain deals not with the scent molecules directly, only with the electrical signals that reach it, and the brain's interpretation of those signals is then perceived as smell.

Beyond just allowing us to enjoy the lovely scents of flowers or delicious foods, the nose has many other important functions, being the beginning of the respiratory passages one of the main conduits between the air we breathe and the blood that transports oxygen to cells throughout the body. When air enters the nose, it encounters tiny hairs known as cilia and is immediately subjected to analysis. Molecules in the air are separated out and examined, and the nature of their smell is forwarded to the brain and determined, all in as little as 30 seconds.

There is also a flawless aerodynamic system in the nose. Air does not directly go to the lungs when it enters the nasal passages. Just like an air-purification unit, the nose prepares air which may be dirty, too hot, cold or dry, using very special filtering systems. Thanks to the special undulating structure in the nose, the air performs a sort of turn, making greater contact with the cilia and network of blood vessels. Thanks to its undulating structure, the air filters 15 cubic meters (19 cubic yards) of air a day,-about equivalent to the volume of air in a room- while cleaning(partially), moistening and warming it.

In order for any technical device to come into existence, there must logically be a talented maker, making a deliberate effort to put the component parts together in a specific order. The system's inimitable creation belongs to Allah(God). Allah(God) has created humans together with the most perfect systems for his survival. Allah(God) is the flawless and peerless Creator of all.
