Why is cartilage a good tissue of choice for the respiratory structures of the larynx, trachea, and bronchi?
Brrunno [24]

Answer:

Cartilage is a type of connective tissue formed of two types of cells, chondrocytes and chondroblasts, and an abundant, highly specialized and vascular extracellular matrix. It is a good tissue of choice because it has the function of supporting soft tissue (tracheal rings, for example), lining the joint surfaces of bones, and promoting the formation and growth of long bones.

Hyaline cartilage is the most common cartilage in the human body. It has a cool translucent bluish-white color and is responsible for the formation of the temporary skeleton in fetal development until this skeleton is replaced by bone tissue. Found mainly supporting the nasal passages, the trachea, and the bronchi, at the ventral end of the ribs and covering the articular surfaces of the long bones.
