Tracheal walls do not collapse when there is less air in it because it is supported by rings of cartilage. What protects the trachea from being collapsed when there is less air in it? The hyaline cartilage in the tracheal wall provides support and keeps the trachea from collapsing. Why do trachea and bronchi not collapse when air is exhaled out during expiration? The trachea does not collapse even if the air pressure is less inside it. Because it has a series of cartilaginous rings which form a relatively rigid arrangement. The C – shaped cartilage rings are present till the trachea bifurcates into the bronchi. This prevents it from collapsing due to pressure changes. What would happen if the wall of trachea is not supported by cartilage rings? Cartilage is a strong but flexible tissues when attached to trachea also known as tracheal cartilage. It supports the wind pipe to stand tall while moving and flexing during breathing. If these cartilage tissues are removed, our wind pipe would collapse. How and why trachea is protected? The trachea serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles. The trachea is lined with a moist mucous-membrane layer composed of cells containing small hairlike projections called cilia. What helps in preventing the collapse of...
Why do walls of trachea not collapse when there is less air in it?
Why is the trachea lined with rings of cartilage? You have rings of cartilage in the trachea. They are incomplete rings. This mechanism, prevents the collapse of the trachea, during the respiration. Incomplete rings allow the constriction of trachea, when something offending enters the trachea. So, on one hand you have rigidity and on the other hand, you have elasticity.
