Full Answer

A person's minute ventilation can increase or decrease based on whether or not he is stressed, exercising or participating in other strenuous activities. An increase in ventilation is the result of an increase in a demand for oxygen combined with an increase in the production of carbon dioxide. A decrease is the result of a decrease in oxygen demand and carbon dioxide production.

    What is the function of the cartilaginous rings of the trachea?

    A:

    The function of the cartilaginous rings of the trachea is to stabilize the trachea and keep it rigid while allowing the trachea to expand and lengthen when the person breathes. If the trachea was not supported in this way, it would simply collapse because of the pressure of the chest. There are between 16 and 20 cartilaginous rings in an average trachea.
