What is tha cartilaginous rings on treachea​

Answer 1

Answer:

Explanation:

A normal trachea (windpipe) has many rings made of cartilage (a strong and flexible tissue). These rings are C-shaped and support the trachea but also allow it to move and flex when your child breathes. Complete tracheal rings are a birth defect in these rings that causes them to be O-shaped instead of C-shaped.
