How do the cartilaginous rings of trachea looks like?

In: Human Anatomy, Trachea [Edit categories]

Answer:

They are C-shaped, with the opening in the back so that when you swallow food, the esophagus expands into the area of the trachea to allow the food (called a bolus) to go down. This process is called deglutition. If they were not C-shaped and positioned this way, your food would not be able to go down into your stomach.
