Summary Introduction
To review:
Match the term trachea with the most closely related description given below:
Superior portion of the pharynx
Bridge of the nose
Nose, nasal cavity, paranasal sinuses, nasal conchae, and nasopharynx
Windpipe
Lobar bronchi
Contains and protects the glottis
Larynx, trachea, bronchi, bronchioles, and alveoli of the lungs
Provide protection for the vocal folds
Positions and stabilizes the larynx
Segmental bronchi
Introduction:
Trachea is also known as windpipe. It refers to the tough and flexible cartilaginous tube, which joins the larynx and pharynx to the lungs. It allows the air to pass and it is present in almost all the air-breathing animals.
