Question

vibration due to exhaled air that results in speech is a function of the: false vocal cords epiglottis glottis true vocal cords question 9 1 pts which one of the following structures is not part of the respiratory zone: respiratory bronchioles primary bronchi alveolar ducts alveolar sacs alveoli

Explanation:

1. For the first question, speech - related vibration from exhaled air is caused by the true vocal cords. False vocal cords are not mainly involved in normal speech production. The epiglottis prevents food from entering the trachea during swallowing, and the glottis is the opening between the vocal cords.
2. For the second question, the respiratory zone is where gas exchange occurs. Respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli are part of it. Primary bronchi are part of the conducting zone which just transports air and does not participate in gas - exchange.

Answer:

1. true vocal cords
2. primary bronchi
