Q

Respiratory System

A

The structures of the upper respiratory system include the nose, nasal cavity, and pharynx (throat). The lower respiratory system includes the larynx (voice box) , trachea (windpipe), bronchi, bronchioles, lungs, and thorax.

The functions of the respiratory system are to bring oxygen into the body and expel carbon dioxide.
