Question

Which of the following has rings of cartilage? *

Trachea

Oesophagus

Buccal cavity​

Answer 1

Answer:

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.

Answer 2

Answer:

trachea

Explanation:

The trachea is surrounded by 16-20 rings of hyaline cartilage; these 'rings' are incomplete and C-shaped.
