What part of the respiratory system prevents the air-passage form collasping?

Information Booster :-

• The ribs protect the lungs and other internal organs.
  
• The spine provides structural support for the body and protects the spinal cord.
  
• The trachea is the windpipe that carries air from the throat to the lungs. It is made up of C-shaped cartilage rings that provide structural support and keep the airway open. The open part of the "C" allows flexibility, while the rigid cartilage ensures that the air passage remains unobstructed and does not collapse, especially during breathing.
