	The '''trachea''', ~~also~~ known as the windpipe, is a tube that connects the ~~[[pharynx]] and~~ [[larynx]] to the [[~~lungs~~]], allowing the passage of air. It is an essential ~~part~~ of the ~~[[respiratory system]]~~ in ~~many air-breathing animals, including humans~~.		The '''trachea''', commonly known as the windpipe, is a vital part of the respiratory system in humans and many other animals. It is a tube that connects the [[larynx]] to the [[bronchi]] of the lungs, allowing the passage of air. The trachea is an essential component of the body's airway and plays a crucial role in respiration.

	==Structure==		== Structure ==

	The trachea is ~~a tube~~ approximately 10 to 12 cm long and 2 cm in diameter. ~~Its wall~~ is ~~made up~~ of ~~incomplete~~ rings of ~~hyaline~~ [[cartilage]]~~, lined with [[respiratory epithelium]]~~. The ~~trachea begins just under~~ the ~~larynx and runs down behind the [[sternum]] (breastbone) and then splits into two smaller tubes~~, the [[~~bronchi~~]], at the ~~[[carina of~~ trachea~~\|carina]], which lead~~ to ~~the lungs~~.		The trachea is approximately 10 to 12 centimeters long and 2 centimeters in diameter in adults. It is composed of 16 to 20 C-shaped rings of [[hyaline cartilage]] that provide structural support and maintain an open airway. The open part of the C-shaped rings faces posteriorly, towards the [[esophagus]], allowing the trachea to expand slightly during swallowing.

	~~==Function==~~		The inner lining of the trachea is made up of [[ciliated pseudostratified columnar epithelium]], which contains [[goblet cells]] that secrete mucus. This mucus traps inhaled particles, and the cilia move the mucus upwards towards the [[pharynx]] where it can be swallowed or expelled.

	The primary function of the trachea is to provide a clear airway for air to enter and exit the lungs. The cartilage rings prevent the trachea from collapsing and blocking the airway. The epithelium lining traps and moves dust and other particles away from the lungs.		== Function ==

	~~==Clinical significance==~~		The primary function of the trachea is to provide a clear airway for air to enter and exit the lungs. It also helps to warm, moisten, and filter the air before it reaches the lungs. The trachea's cilia and mucus play a critical role in trapping and expelling foreign particles and pathogens.

	Diseases and conditions that can affect the trachea include [[tracheitis]], [[tracheal stenosis]], [[tracheomalacia]], and [[tracheobronchomalacia]]. Tracheal obstruction can be life-threatening. Medical procedures involving the trachea include [[tracheostomy]] and [[tracheal intubation]].		== Clinical significance ==

	==~~See also~~==		The trachea can be affected by various medical conditions, including:
	* [[~~Bronchus~~]]
			* '''[[Tracheitis]]''': Inflammation of the trachea, often due to infection.
			* '''[[Tracheal stenosis]]''': Narrowing of the trachea, which can be congenital or acquired.
			* '''[[Tracheomalacia]]''': Weakness of the tracheal walls, leading to collapse during breathing.
			* '''[[Tracheoesophageal fistula]]''': An abnormal connection between the trachea and the esophagus.

'''Trachea'''

The '''trachea''', also known as the windpipe, is a tube that connects the [[pharynx]] and [[larynx]] to the [[lungs]], allowing the passage of air. It is an essential part of the [[respiratory system]] in many air-breathing animals, including humans.

==Structure==

The trachea is a tube approximately 10 to 12 cm long and 2 cm in diameter. Its wall is made up of incomplete rings of hyaline [[cartilage]], lined with [[respiratory epithelium]]. The trachea begins just under the larynx and runs down behind the [[sternum]] (breastbone) and then splits into two smaller tubes, the [[bronchi]], at the [[carina of trachea|carina]], which lead to the lungs.

==Function==

The primary function of the trachea is to provide a clear airway for air to enter and exit the lungs. The cartilage rings prevent the trachea from collapsing and blocking the airway. The epithelium lining traps and moves dust and other particles away from the lungs.

==Clinical significance==

Diseases and conditions that can affect the trachea include [[tracheitis]], [[tracheal stenosis]], [[tracheomalacia]], and [[tracheobronchomalacia]]. Tracheal obstruction can be life-threatening. Medical procedures involving the trachea include [[tracheostomy]] and [[tracheal intubation]].
