Which statement describes the function of the turbinates in the respiratory tract?
A) Turbinates contain the vibrissae, which serve as an initial "filter" to screen particulate matter from the air.
B) Turbinates serve as baffles to provide a large, mucus-covered surface area over which air must pass before reaching the pharynx.
C) Turbinates lighten the bones of the skull and serve as resonating chambers for speech.
D) Turbinates are lined with a ciliated membrane and form two cartilaginous folds that serve as the vestibular vocal cords.

Question

Quizplus · Accepted Answer

The turbinates, also known as nasal conchae, are bony structures in the nasal cavity that protrude into the respiratory space. They increase the surface area of the nasal cavity, creating more friction and resistance for the air passing through. This allows for better humidification, warming, and filtering of the air before it reaches the lungs. The increased surface area is also covered in a layer of mucus, which helps trap particles and prevent them from entering the respiratory system.
