HAP: The Respiratory System Part 1
List the organs forming the respiratory passage way(s) in descending order until the alveoli are reached.
Distinguish between conducting and respiratory zone structures.
What is the common function of the respiratory zone structures?
What are the four main events of respiration?
Complete the following statements concerning the nasal cavity and other structures: Air enters the nasal cavities of the respiratory system through the _______________(1). The nasal cavity is divided by the midline _______________(2). The nasal cavity muscosa has several functions. Its major functions are to ______________(3), ________________(4), _________________(5) the incoming air. Mucous membrane-lined cavities called _______________(6) are found in several bones surrounding the nasal cavities. They make the skull less heavy and probably act as resonance chambers for ________________(7). The passageway common to the digestive and respiratory systems, the _________________(8), is often referred to as the throat; it connects the nasal cavities with the _________________(9) below. Clusters of lymphatic tissues, ____________(10) are part of the defensive system of the body.
