The respiratory system is made up of what three functions
Pulmonary Ventilation, Respiration, and Perfusion
Normal respiratory system function depends of what 3 factors functioning properly
Airway (nutrients to alveoli/wastes out from alveoli), Alveoli (exchange), Cardiovascular System (nutrients from alveoli to body/wastes from body to alveoli)
The 'airway' begins at the ____ and ends at the ____ . The upper airway ends at the _____. The lower airway starts at the ____ and ends at the ____
Mouth / terminal bronchioles / epiglottis / trachea / terminal brochioles
The function of the upper airway is to ____
Warm, Filter, Humidify (inspired air)
The function of the lower airway is to _____
Conduct (air), Mucocilial Clearance, Pulmonary Surfactant (production)
T/F... the right lung has 3 lobes, and the left lung has 2 lobes
True
The right lung has ___ brochopulmonary segemts and the left lung has ____
10 / 8
T/F..the walls of alveoli are made up of columnar epithelial cells
False,.... squamous
____ is a detergent-like phospholipid that reduces the surface tension between moist membranes of the alveoli, preventing their collapse
Surfactant
The lungs and thoracic cavity are lined with a serous membrane called the ______
Pleura
What covers the lungs? what covers the thoracic cavity?
Visceral Pleura / Parietal Pleura
Lungs are held inbetween the two pleural layers with ____ , which acts as a ____
Pleural Fluid / Lubricant
The constant negative intrapleural pressure, along with the pleural fluid hold the lungs _____
In an expanded position
_____ refers to movement of air into/out of the lungs
Pulmonary Ventilation
_____ involves gas exchange between the atmospheric air in the alveoli and blood in the capillaries
Respiration
