What is the upper airways?
The upper airways indicates an anatomical structures set that cooperate on air transfer to the lungs. Together, the pharynx, larynx, nose, nasal cavity and mouth form the upper airways, although these structures have different functions. For example, larynx or voice box controls speech and pharynx or neck is used to transport food to the stomach. The upper airways are located just above the trachea. Anything under this area is considered to be the lower airways. The nostrils are divided into two compartments through which air is inhaled. The air is then taken over the bony tubular holes, referred to as a cone that are considered to be the bones of the face. It then passes through the internal nr, which contains capillaries, small hairs and hosts. These small nasal hairs act as a filter and adhere to particles or bacteria to cause disease or damage fine inner nasal passages. After the air passes through the internal nast, it enters the neck. This nasal pharynic contains adenoids or almonds that can be seen inthe back of the neck. They can capture contaminants or bacteria that can also be harmful when ingested. The internal nare also contains eustachian tubes that are used to stabilize air pressure in the ears.
The larynx is commonly referred to as a voice box. It is used to produce sounds and also to block small food particles that could otherwise enter the airways. Vocal cords or folds placed in the larynx control the volume or spacing of the voice. They are located directly above the esophagus and trachea. Here the lower and upper airways are connected.
The upper respiration of RACT is a common disease because it can evolve in the area of the nose, neck or mouth. These infections are considered a cold and can produce different symptoms depending on where they develop. Sinus or nasal infection can produce nitter or dripped nose, while the infected larynx can cause voice sounds. InfensThe bump of the upper respiratory tract can be either viral or bacterial. There is no cure for infection of viral airway viral tract, but bacterial infection can be treated with antibiotics.
