The trachea, or windpipe, is a tube extending from the larynx to the bronchi in mammals, and from the pharynx to the syrinx in birds, carrying air to the lungs. It is lined with ciliated cells which push particles out and cartilage rings which reinforce the trachea and prevent it from collapsing on itself during the breathing process. These numerous cartilaginous half-rings, located one above the other along the trachea have open ends adjacent to the oesophagus. The rings are connected by muscular and fibrous tissue, and they are ...

A cough is a sudden, often repetitive, spasmodic contraction of the thoracic cavity, resulting in violent release of air from the lungs, and usually accompanied by a distinctive sound. Cough is an action your body takes to get rid of substances that are irritating the air passages. A cough is usually initiated to clear a buildup of phlegm in the trachea; air may move through this passage at up to 480 km/h (300 mi/h) during a contraction. Coughing can also be triggered by a bolus of food going down the trachea instead of the esophagus, ...

The airways are those parts of the respiratory system through which air flows, to get from the external environment to the alveoli. The airway begins at the mouth or nose, and accesses the trachea via the pharynx. The trachea branches into the left and right main bronchi at the carina, situated at the level of the second thoracic vertebra. The bronchi branch into large bronchioles, one for each lobe of the lung. Within the lobes, the bronchi further subdivide some 20 times, ending in clusters of alveoli. The epithelial s ...

As a verb, to choke generally means to restrict airflow, or to suffer restricted airflow, whether caused by such a device or by accidental obstruction; see choking. As nouns or adjectives related to that verb, choke and choking may refer to several things: In vertebrate physiology, medicine, and related contexts, a choke or choking is an occlusion of the airway that prevents respiration. In horses, however, choke is an obstruction of the esophagus, rather than the trachea ...

The vocal tract is that cavity in animals and humans, where sound that is produced at the sound source (larynx in mammals; syrinx in birds) is filtered. In birds it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak. In mammals it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity, and in some nonhuman mammals maybe also the airsacs.

Hemoptysis (or "coughing up blood") is the expectoration of blood or of blood-stained sputum from the bronchi, larynx, trachea, or lungs (e.g. in tuberculosis or other respiratory infections). It is not the same as Hematemesis, which refers to vomiting up blood. Hemoptysis - Causes. This can be due to lung neoplasm, tuberculosis, bronchiectasis, coccidioidomycosis, or pulmonary embolism. Rarer causes include hereditary hemorrhagic telangiectasia (HHT or Rendu-Osler-Weber syndrome). ...

A bronchus (plural bronchi, adjective bronchial) is a caliber of airway in the respiratory tract that conducts air into the lungs. No gas exchange takes place in this part of the lungs. Bronchus - Anatomy. The trachea (windpipe) divides into two main bronchi, the left and the right, at the level of the sternal angle. The right main bronchus is wider, shorter, and more vertical than the left main bronchus. The main bronchi subdivide into two and three secondary bronchi that each serve t ...

In ancient geography, Cilicia ("Ki-LIK-ya") formed a district on the southeastern coast of Asia Minor (modern Turkey), north of Cyprus. Cilicia extended along the Aegean coast east from Pamphylia, to Mount Amanus (Giaour Dagh), which separated it from Syria. North of Cilicia lie the rugged Taurus Mountains that separate it from the high central plateau of Anatolia, which are pierced by a narrow gorge, called since Antiquity the Cilician Gates. Ancient Cilicia was naturally divided into Cilicia Trachea and Cilicia Pedias ...

A few chokeholds (such as one version of Judo's hadaka jime) work by constricting the opponent's trachea, which restricts the air supply and causes pain and possibly physical damage but may not result in unconsciousness quickly. The more efficient chokeholds, the "blood chokes", do not attempt to cut off the opponent's air supply; rather, they work by cutting off the blood supply to the brain by compress ...

The trachea (windpipe) divides into two main bronchi, the left and the right, at the level of the sternal angle. The right main bronchus is wider, shorter, and more vertical than the left main bronchus. The main bronchi subdivide into two and three secondary bronchi that each serve the left and right lungs, respectively. The lobar bronchi divide into tertiary bronchi. Each of the segmental bronchi supplies a bronchopulmonary segment. A bronchopulmonary segment is a division of a lung that is separated from the rest of the lung by a connectiv ...

The initiating event in developing chronic bronchitis appears to be chronic irritation due to inhalation of certain substances (especially cigarette smoke). The earliest clinical feature of bronchitis is increased secretion of mucus by submucousal glands of the trachea and bronchi. Damage caused by irritation of the airways leads to inflammation and infiltration of the lung tissue by neutrophils. The neutrophils release substances that promote mucousal hypersecretion. As bronchitis persists to become chronic bronchitis, a substantial increas ...

It is inserted into the trachea, generally via the mouth, but sometimes through the nares of the nose (e.g. in extensive mouth surgery) or even through a tracheostomy. The process of inserting a ETT is called intubation. Intubation usually requires general anaesthesia and muscle relaxation but can be achieved in the awake patient with local anaesthesia or in an emergency without any anaesthesia, although this is extremely uncomfortabl ...
