The microscopic cilia function to move mucus toward the pharynx.
An inflammation of the lower respiratory tract that involves the airways of the lungs is called pneumonia.
The small leaf-shaped cartilage that projects upward behind the tongue and hyoid bone is the epiglottis.
The vibrissae function as filters
The air-containing spaces that open, or drain, into the nasal cavity are called paranasal sinuses.
