Answer:
Trachea do not collapse because they lies to the anatomy of trachea.
Explanation:
Trachea has a very solid built. It has cartilaginous rings of C shaped, also called tracheal rings around the trachea for the support. They are incomplete circles, allowing slight collapse or inflation.
Beside this, there is surfactants secreted from type 2 alveolar cells, which reduces the surface tension of water, thereby reducing the tendency to collapse. This is why, trachea doesn’t collapse during forceful inhalation.
