<Tr> <Th> FMA </Th> <Td> 7394 </Td> </Tr> <Tr> <Td_colspan="2"> Anatomical terminology (edit on Wikidata) </Td> </Tr> <P> The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air - breathing animals with lungs . The trachea extends from the larynx and branches into the two primary bronchi . At the top of the trachea the cricoid cartilage attaches it to the larynx . This is the only complete ring, the others being incomplete rings of reinforcing cartilage . The trachealis muscle joins the ends of the rings and these are joined vertically by bands of fibrous connective tissue--the annular ligaments of trachea . The epiglottis closes the opening to the larynx during swallowing . </P> <P> The trachea develops in the second month of development . It is lined with an epithelium that has goblet cells which produce protective mucins . An inflammatory condition, also involving the larynx and bronchi, called croup can result in a barking cough . A tracheotomy is often performed for ventilation in surgical operations where needed . Intubation is also carried out for the same reason by the inserting of a tube into the trachea . From 2008, operations have transplanted a windpipe grown by stem cells, and synthetic windpipes; their success is however doubtful . </P>

Where is the windpipe located in the human body
