Spit everywhere - transmission n/med tuberculosis?

From;  Author:Stand originally Position:home>Condition exchange>

Phlegmy, it is the secretion of human body respiratory tract, it is through bronchus cilium motion epithelial ciliary moves, drive to the upper respiratory tract from lung, finally, the normal cough that carries a person is reflexed from tracheal inside outside expectorate eduction body, normal person is phlegmy very few, just hold respiratory tract wet and excretive a few mucous. But when the person the inspiratory excitant gas, dust, bacterium that cause disease, virus harmful microbial when, the upper respiratory tract produces inflammation possibly, or lung happening disease, respiratory tract can be secreted increase, phlegmy quantity can increase, and phlegmy property also can produce change, can by stick phlegmy become yellow pus phlegmy. For instance: In bronchiectasis disease, tuberculosis is empty when forming, when inflammation of lobar fester sex, the quantity with yellow phlegmy pus can increase, and inside can contain many pathogenic bacteria.

Respiratory tract is secreted a few mucous it is normal, it can have effect of a protection to the person. When the person inspiratory colder with dry air when, it is OK to pass respiratory tract the air containing oxygen inside intromit lung undertakes wet and add lukewarm, adsorption is in the contains a bacterium dust grain in the dust that also can make induction air medium, poisonous other grain and air on wet bronchus wall, through bronchus epithelial cilium moves, push to the upper respiratory tract, outside adopting cough eduction system, the action that protects lung reached since.

Lung is interlinked directly through respiratory tract and outside, airy contaminant is varied, the dry grain after also bearing with phlegmy fluid and dust are united in wedlock among them, the breath that carries a person is inspiratory lung, once human body resistance drops, so, respiratory system produces inflammation and the opportunity of go to the bad increases greatly greatly. Classics scientists study, as a result of,think the characteristic of respiratory system structure, affect lung cause disease microbial much and complex. Say the patient can pass the secretion of respiratory system again again, the eduction of phlegmy fluid, sneeze can pollute air again, can make a person inspiratory again. The contagion of such go round and round and infection, so, it is very fast that the contagion popularity of respiratory tract is infected. Besides, the time that n/med tuberculosis bacili survives in dry dust is very long, so, the harm is greater also.

The way that respiratory tract spreads, basically be to passed phlegmy fluid to pollute air, polluted the dust in air. Somebody is passed determine, normal person wants 24 hours at least everyday inspiratory 10 ~ the air of 12 stere, cannot keep the oxygen that normal activity place wants the person otherwise. In the air of these more than 10 stere, also can be had to contain the oxygen of 20.9% only by what the person uses, can be imagined, the thing that place of how many human body does not need is contained in the air of this more than 10 stere, including harmful toxicant and the dry grit that carry a bacterium among them. How to reduce these so needless is harmful material even is inspiratory, purify our environment with respect to need, reduce the pollution to the environment.
