The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung..
Keeping this in consideration, where does the trachea begin and end?
The trachea begins at the lower edge of the cricoid cartilage of the larynx, and ends at the carina, the point where the trachea branches into left and right main bronchi.
One may also ask, what happens in the trachea? Function. The trachea serves as the main passageway through which air passes from the upper respiratory tract to the lungs. As air is pulled into the trachea during inhalations, it is warmed and moisturized before entering the lungs. Subtle contractions of the trachea occur involuntarily as part of normal respiration.
Besides, what side is your windpipe on?
The food and air are directed down the right tube thanks to your epiglottis, which is a movable flap of tissue. It opens when you breathe, but then closes over your windpipe when you swallow so food goes down your esophagus, which is the passageway from the throat to the stomach.
Where is the epiglottis located?
The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
