What is intercostal muscles?

The number of thoracic bones in the spine
What is twelve?
These three parts make up the upper respiratory tract below the nasal cavity
What is the nasopharynx, oropharynx, and laryngopharynx?
These cells break down foreign particles
This clears fluid from interstitial space to maintain fluid balance and remove cell debris
What is lymphatic circulation?
This branch of the PNS sends unconscious signals to and from the brain to affect smooth muscle
What is the autonomic nervous system/branch?
The untrained eye may confuse the lines of this bone as a pneumothorax on chest x-ray
What is the scapula?
The cover over the vocal cords during swallow
What is the epiglottis?
Type II pneumocytes
What is create surfactant to prevent alveolar collapse?
The left lung does not have this
What is the horizontal fissure?
This system causes increased salivation, bronchoconstriction, and bradycardia
What is the parasympathetic nervous system?
Fractures in this bone make intubation difficult
What is the maxilla or mandible?
Point where the mainstem bronchi bifurcates
What is the carina?
The diaphragm is primarily maintained by these parts
What is C3-4-5 with their phrenic nerves?
Muscles that are active when ventilatory demand abnormally increases, such as in pain or in fear
This a sympathetic fiber neurotransmitter
Not a bone, yet provides structure to the trachea
What is cricoid cartilage?
The region the lymphatic system dumps into and around the lungs
What is the hilum or hilar?
What is bronchial circulation?
Term describing decreased PA BP causing increased bronchial arterial blood flow to the negatively affected area
What is a compensatory relationship?
Low pressure, low resistance system
What is pulmonary circulation?
Boney shelves that cause turbulent flow and are sensitive to external manipulation
What are turbinates, or conchae?
