What is the bronchiole terminal?

Terminal bronchiole is small airways carrying air inward and out of the lungs. The second to the last branch of Bronchi, the terminal bronchiole is the division of bronchiols and branches itself into respiratory bronchiols. These bronchioles directly penetrate the alveoli, buds similar to bags filled with capillaries where oxygen and carbon dioxide enter and leave blood circulation. This respiratory airway is known as the bronchiole of the terminal because it is the last way of the conductive zone. The guide zone includes all the respiratory system segments up to this point - between them nose, trachea, bronchi and bronchioles - and the function to increase the temperature and add humidity to the incoming air and also filter pathogens.

We start where it enters the nostrils through the nostrils, the inhaled air is swept into the nasal cavity and backwards into the pharynx or neck. Passes through the larynx, better known as the voice box, is drawn into the tracheaBy effecting the membrane muscle under the lungs, which fills the underside of the thoracic cage and acts like sucking when it withdraws. The air was drawn into the trachea, which is divided into either the lungs through a bronchi, which contains many small branches, bronchioles. If the lungs were a promising tree, then the trachea or wind would be a suitcase, both bronchi would be every branch, bronchioles that divide these branches, end bronchioles on the limbs on the limbs.

As the last part of the conductive zone, the bronchiole terminal performs the same function as the segments in front of it. It heats the air, contributes with humidity, filters and supports continued air flow by expanding to reduce any resistance that comes the coming air, because the Makes gets to the alveoli. The last two functions are of particular importance, because the air that reaches each bronchiole terminal is almost warm to body temperature and moistened.

At this point, the air was also quite well deprived of pathogens. InThe facts of the terminal bronchioles contain several cilled cells, cells found in the entire conductive zone, whose task is to collect allergens and other undesirable particles carried in inhalation air. Instead, they are lined with a type of unknown epithelial cell known as Clara cell, which excludes protein known as Secret Protein Clara Cell (CCSP), whose enzymes break toxins found in the air and also suspended in the lung fluid.

In addition to defense, the Clara Bronchiole terminal cells help remain open as air passes through it. They release the type of substance known as a surface -active substance that reduces the voltage of the epithelial bronchiole lining. This allows the airway to be expanded as Air is inhaled. On the contrary, because the air has expired from the lungs, the surface active substance prevents the vacuum formed from the suction of bronchiole in the shape of the tube.
