The airway system transports air (O2 and CO2) _____ and ____ the lungs - ANSWER to
and from
What does the alveolar system do?
-oxygenates ___
-removes ___ - ANSWER oxygenates venous blood
removes CO2 from blood
What is the function of the upper respiratory system? - ANSWER Warm, filter, humidify
inspired air
What are the components of the upper respiratory system? - ANSWER Nose, Pharynx,
Larynx, Epiglottis
What is the function of the lower respiratory system? - ANSWER Conduction of air,
mucociliary clearance, production of pulmonary surfactant
What are the components of the lower respiratory system? - ANSWER Trachea, right
and left mainstem bronchi, segmental bronchi, terminal bronchioles
The lungs are composed of _____ _____ - ANSWER elastic tissues
(alveoli, surfactant, pleura)
What are cilia? - ANSWER Tiny hair-like projections that propel trapped material and
accompany mucous toward the upper airway to be removed with coughing
, What are alveoli? - ANSWER Small air sacs;
SITE OF GAS EXCHANGE
What is the site of gas exchange? - ANSWER Alveoli
What is surfactant? - ANSWER Phospholipid
Reduces surface tension between the moist membranes of the alveoli
What is the Parietal Pleura? - ANSWER Lines the thoracic cavity
What is the Visceral Pleura? - ANSWER Covers the lungs
What is the Pleural Space? - ANSWER Located between the parietal and visceral
pleura.. contains pleural fluid that acts as a lubricant to assist in respiration

Where do chest tubes sit? - ANSWER In the pleural space
Two components of ventilation are: - ANSWER inspiration and expiration
What is inspiration? - ANSWER The active phase of ventilation
Involves movement of the muscles and the thorax to bring air into the lungs
