the purpose of the hyaline cartilage C-rings in the respiratory system, or more specifically in the trachea is to allow for the expansion of the underlying esophagus when food or liquids pass through.


The open ends of these incomplete rigs are directed posteriorly, and smooth muscle and connective tissues fill the gaps between the ends, These cartilaginous rings prevent the trachea from collapsing and blocking the airway. The soft tissues that complete the rings in the back allow the nearby esophagus to expand as food moves through it to he stomach.
