Question

Quizplus · Accepted Answer

Nasal conchae and alveoli both increase the surface area of the respiratory system. The nasal conchae are bony structures within the nasal cavity that increase the surface area and create turbulence to help warm, humidify, and filter the air. The alveoli are small air sacs within the lungs where gas exchange occurs, and their numerous and intricate structure greatly increases the surface area available for gas exchange. The larynx, on the other hand, is a structure that connects the pharynx to the trachea and is responsible for producing sound, but it does not significantly increase the surface area of the respiratory system. Therefore, the correct answer is choice D.
