Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The organ of the respiratory system that is kept open by rings of cartilage is the:
A
nose
B
pharynx
C
larynx
D
trachea
Explanation: 

Detailed explanation-1: -The trachea (windpipe) is the part of the airway that continues below the larynx (LAIR-inks). The walls of the trachea (TRAY-kee-uh) have stiff rings of cartilage to keep it open. The trachea is also lined with cilia, which sweep fluids and foreign particles out of the airway to keep them out of the lungs.

Detailed explanation-2: -The cricoid cartilage is a hyaline cartilage ring which fully encircles the trachea and composes the inferior-most boundary of the laryngeal skeleton. The term “cricoid, ” (Greek, krikos meaning “ring-shaped”) refers to the signet-ring resemblance of the cricoid cartilage.

Detailed explanation-3: -In the trachea, or windpipe, there are tracheal rings, also known as tracheal cartilages. Cartilage is strong but flexible tissue. The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing.

Detailed explanation-4: -The hyaline cartilage in the tracheal wall provides support and keeps the trachea from collapsing.

Detailed explanation-5: -Rings of cartilage are present in the trachea to prevent its collapse when the air is not passing through it. The cartilage is a flexible connective tissue, and it supports the trachea while still allowing it to move and flex during breathing.
