Question

Consider the location of the trachea in relation to the surrounding structures. Why might it be important that hyaline cartilage does not completely surround the trachea?

Answer 1

Ans:-

Location of trachea in relation to the surrounding structures is as follows:-

Trachea just begins at the lower edge of the cricoid cartilage of the larynx ( voice box) and runs down behind the sternum and ends at the carina where trachea divides into two smaller tubes called primary bronchi for each lung.

Hyaline cartilage does not completely surround the trachea and it is important because the purpose of these incomplete hyaline cartilages is to allow the expansion of the underlying esophagus when food or liquids pass through .
