Respiratory System

Warms, moistens, and filters air as it is inhaled

Passageway for air, leads to trachea

The voice box, where vocal cords are located

Keeps the windpipe open. Trachea is lined with fine hairs

Two branches at the end of the trachea, each lead to a lung

A network of smaller branches leading from the lung tissue

The functional respiratory units in the lung where gases are exchanged
