How is cold nasal obstruction to return a responsibility? Did the virus attack you
First: when the cold virus invades the human body from the respiratory tract and causes a cold, the virus moves in the nasal cavity, causing the nasal mucosa to swell, and the nose will secrete more extra water or mucus (secretion) to help us naturally expel the dead virus from the body. If the clear nasal water turns into yellow nasal mucus, it means that the nasal cavity is inflamed by other bacteria or viruses. The yellow nasal mucus is like pus.
Second: the inner surface of the nasal cavity of healthy people is lined with a complete layer of mucous membrane, on which there are many goblet cells with secretory function. There are mucous glands under the mucous membrane, which constantly carry out secretory activities. The water secreted is used to moisten the inhalation air. In addition, the mucous glands often secrete a small amount of mucus, which is evenly distributed on the surface of the mucous membrane.
Third: it has strong stickiness and can absorb dust and microorganisms in the air. Mucus also contains lysozyme, which can inhibit and dissolve bacteria. Under normal circumstances, relying on the cleaning effect of this mucus, when the inhaled air reaches the back half of the nasal cavity, there are almost no microorganisms.
matters needing attention
Under normal circumstances, the liquid secreted by nasal mucus gland and evaporated liquid are in relative equilibrium. Once the nasal cavity pathological changes, secretions can increase, and the formation of nasal mucus.
