Human respiratory system begins with the nose. The structure of the hairs in your nose, watery surface and near-surface capillaries are found. These structures of the air taken in during breathing, and dust retention of microbes, allows warming and moistening.
The nose of fragrant flowers or the smell of appetizing dishes beyond to ensure that we perceive, a very important function, which is the organ. Taken together with the air we breathe oxygen from the air that carries blood to all the cells of our bodies is one of the main link road between. In short nose and olfactory organ, as well as the beginning of the respiratory tract is of great importance. The nose consists of two chapters in the "cilia" called hairs and mucus secretions are called. run or dye When air enters through the nose encounters with them and immediately subjected to analysis. Separated from the air molecules are analyzed and transmitted to the brain where smell is determined by what is given and according to her response. The whole process only takes place within a very short period such as 30 seconds.
Terms of aerodynamics in the nose, there is also a flawless design. When it enters the air does not go directly into the trachea. Nose, almost run or dye like an air filter system with a very special from the outside, dirty, hot, cold or humid weather makes it ready for the lungs. Through special curved run or dye structure in the nose makes a round trip air here. Thus nose hairs found in the wall and would have greater contact with the vascular network. That system allows curved nose daily for 15 m3 of air filters, cleans, moisturizes and heat. This amount is approximately equal to the air in a room. But the dirty air that comes to mind here should not just dusty air. The dust with air as well as bacteria, pollen, etc.. approximately 20 billion as foreign substances enter the body through the nose becomes blocked in the private system.
Dust and all kinds of harmful bacteria left in the air conditioning system in the nose, after this procedure, one in each nostril three passes over undulating structures. Attached to the tiny hairs in this case, wherein the impurities are then neutralized with antibacterial mucus. Meets these undulations air changes direction and hit the wall of the nasal cavity.
Hit here in the mucosal fluid is maintained. Removal of foreign bodies of the respiratory air is very comprehensive and is very sensitive. The slightest error, remember, and not allowed to jump. Because of a body of a bacteria or harmful to the lungs to pass such a delicate organ, can create negative effects on people's health. However, in spite of everything harmful objects pass through the nose to achieve, in case there is a second protection mechanism. If the objects that can pass through the nose if they are held in the respiratory tract. Burn the set temperature of the air in your lungs cleaned and is ready to go. Windpipe to the lungs is the path to be followed to achieve. Pharynx
At first the nose breathing clean air at a later stage taking run or dye the lead in the body will go down on a little more. Areas where the air through the nose and windpipe is now then. Trachea, located between the pharynx and lung. Cartilage cyclic structure. Sağlar.ağız transmission of air space in the lungs in the last part of the trachea connects the pharynx. 10-12 cm long and 2 cm in diameter to the throat is called the initial portion of the tubing. Epithelium of the vocal cords in the larynx has occurred and the extension, tension is adjusted with various shades of muscle tone ejects.
Of the trachea, esophagus flat which is adjacent to the rear face and the inner face of the epithelial cells are furnished with movable bearing sills. Consisting of these cells under the glandular epithelium, as found in the cells of which secretion of goblet cells. These cells are the interests of a substance called run or dye mucus. Creates a thin layer of mucus on moving sills. Thin mucus layer, and ensures that they stay moist epithelial surface, as well as respiratory and other foreign matter from entering the amount of dust in the air. These hairs are constantly in the opposite run or dye direction toward the mouth of the lung do whip-like motion. In this way, smaller parts of the hairs falling onto them progressed up the throat and lungs gets away from. Windpipe joins the esophagus in the throat area, and some bacteria accumulated in the waste particles into the esophagus run or dye passes. Parts of the swallowing reflex in the throat starts.
That the waste substances and all bacteria run or dye in the lungs which can cause disease by swallowing the disintegration in the stomach and gastric acid is transmitted. When woken up in the morning feeling in the throat is the reason for the occupancy and volume changes
