The olfactory organ consists of the left and right nasal passages, which are connected to the outside world through the nostrils, and in between them is the nasal diaphragm, which is connected to the mucous membranes that cover the entire inner wall of the nasal passages. The role of the olfactory senses is to allow the body to feel a variety of different odors.

The olfactory receptors are located at the top of the nasal cavity, called the olfactory mucosa, which is located not in the pathway for the flow of respiratory gases, but rather for the turbinate of the nose to cover the bulge. Air with odors can only reach the olfactory receptors in a gyratory airflow.

If you have chronic rhinitis, the hypertrophy of the turbinates often affects the airflow to the olfactory receptors, causing olfactory dysfunction.

The sense of smell disappears: if you can't smell the odor for no apparent reason, it's called loss of smell, and this condition is due to nasal obstruction, the air can't reach the sensitive area of the nose; followed by injury or damage to the olfactory nerves, as well as the olfactory region of the brain has a disease. People who lose their sense of smell can reliably distinguish salty, sour and bitter flavors with their tongues, but not scents.

Losing the sense of smell has a great impact on people, first of all, the disappearance of the sense of smell is generally caused by disease, colds or rhinitis will affect the nose people breathe, resulting in poor breathing, dry mouth and tongue, which in turn affects the sleep, the feeling is very bad; secondly, the loss of the sense of smell can not be smelled, such as the fragrance of flowers, meat, fragrance ...... etc., it is a great loss for eating and dining, life has no flavor. Eating anything is not flavorful. Once again the olfactory organs are two entrances and exits of our body's internal communication with the external environment. Therefore, they take on certain vigilance tasks. People's keen sense of smell can avoid harmful gases (gas bombs in war, liquefied petroleum gas ......) from entering the body.

Rhinitis, or inflammatory diseases of the nasal cavity, is an inflammation of the nasal mucosa caused by viruses, bacteria, allergens, various physical and chemical factors, and certain systemic diseases. The main pathological changes of rhinitis are congestion, swelling, exudation, hyperplasia, atrophy or necrosis of the nasal mucosa. I once had, especially to the seasonal change of time exceptionally painful, every day is tears, snot a big, ate a lot of drugs, treatment for many times are not good, and then began to exercise, every day adhere to the jogging, be sure to sweat, important thing to say three times, sweat, sweat, sweat, and now adhere to the sixth year, rhinitis unknowingly did not have, the original face peeling and also, I don't know! Is not related to exercise, anyway, weight down twenty pounds on the body of a variety of problems are not.
