The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.
Laryngotracheal stenosis (Laryngo-: Glottic Stenosis; Subglottic Stenosis; Tracheal: narrowings at different levels of the windpipe) is a more accurate description for this condition when compared, for example to subglottic stenosis which technically only refers to narrowing just below vocal folds or tracheal stenosis.
An important section of it is the epiglottis, separating the esophagus from the trachea (windpipe), preventing food and drinks being inhaled into the lungs. The throat contains various blood vessels, pharyngeal muscles, the nasopharyngeal tonsil, the tonsils, the palatine uvula, the trachea, the esophagus, and the vocal cords.
Laryngospasm is an uncontrolled or involuntary muscular contraction of the vocal folds. [1] It may be triggered when the vocal cords or the area of the trachea below the vocal folds detects the entry of water, mucus, blood, or other substance.
The tip of the endotracheal tube is positioned above the carina (before the trachea divides to each lung) and sealed within the trachea so that the lungs can be ventilated equally. [25] A tracheostomy tube is another type of tracheal tube; this 50–75-millimetre-long (2.0–3.0 in) curved metal or plastic tube is inserted into a tracheostomy ...
In humans, the pharynx is part of the digestive system and the conducting zone of the respiratory system. (The conducting zone—which also includes the nostrils of the nose , the larynx , trachea , bronchi , and bronchioles —filters, warms and moistens air and conducts it into the lungs ). [ 1 ]
Following these function tests a special type of Chest CT scan or a bronchoscopy will be ordered. The results of the scan and bronchoscopy [9] will display the status of the condition. A mild case of tracheobronchomalacia would be if the patient's trachea condenses 50% of its normal space when exhaling.
Tracheomalacia occurs when the walls of the trachea collapse. This can happen because the walls of the windpipe are weak, or it can happen because something is pressing on it. This may include hypotonia of the trachealis muscle. [3] The whole windpipe can be affected, or only a short piece of it.
