If in a person, the trachea and bronchi of the respiratory system do not have tracheal rings, then which of the following would be the result?
Options:
Answer:
A
Solution:
The trachea and bronchi are supported by incomplete C-shaped cartilaginous rings. These rings provide structural support and prevent the airways from collapsing during inspiration when the pressure inside the respiratory tract decreases. If these rings are absent, the trachea and bronchi airways would collapse, obstructing the flow of air.
Answer: Trachea and bronchi airways collapse
