-Pharynx

What is a part of the lower respiratory tract?

-Larynx

-Trachea

-Bronchial tree

-Lungs

Nose

External Nares, internal hairs

Nasal Cavity

The hollow space behind the nose and between the hard palate and

Sinuses

-air-filled spaces in the maxillary, frontal, ethmoid, and

sphenoid bones of the skull

-reduce the weight of the skull and serve as voice

resonant chambers.

Pharynx

-move food & air; aid in sound production
