Trachea

Friday, September 21, 2012

The trachea is a membranous tube that connects the larynx to the bronchi, functioning as an air passage during breathing. It consists of cartilaginous rings joined together by annular ligament. Commonly known as windpipe, the trachea measures about 10 cm in length and 1.5 cm in width, and divides into two branches: the right and left bronchi. Situated in front of the esophagus, a surgical incision (hole) made in the trachea, through the neck, just below Adam's apple, to rescue and save the life of someone who has choked on a piece of food or object; this is called tracheotomy.
