PATHOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The trachea (windpipe) is made up of cartilages (also called tracheal rings). Normally tracheal rings are “C” shaped.

Detailed explanation-3: -The cartilage of the trachea is considered hyaline cartilage: simple, transparent, and made primarily of collagen. The trachealis muscle connects the open ends of the C-shaped rings of cartilage and contracts during coughing, reducing the size of the lumen of the trachea to increase the air flow rate.
