Describe the structure of the trachea.
(32) 
Answered by Examlex AI CopilotThe trachea, also known as the windpipe, is a tubular structure made of cartilage rings and smooth muscle. It is located in the neck and chest and connects the larynx to the bronchi of the lungs. The trachea is approximately 4-5 inches long and about 1 inch in diameter.
The trachea is lined with a mucous membrane that contains ciliated cells, which help to trap and remove dust, bacteria, and other foreign particles from the air we breathe. The cartilage rings provide support and prevent the trachea from collapsing, while the smooth muscle allows for flexibility and movement during breathing.
At the top of the trachea is the larynx, which contains the vocal cords, and at the bottom, it branches into the left and right bronchi, which lead to the lungs. The trachea also contains a layer of connective tissue and blood vessels that supply oxygen and nutrients to the cells of the tracheal wall.
Overall, the structure of the trachea is designed to allow for the passage of air to and from the lungs while providing support and protection for the delicate tissues within.
