Airway ✅The passageway by which air enters and leaves the body. The structures of
the airway are the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs.
Alveolar Ventilation ✅The amount of air that reaches the alveoli.
Artificial Ventilation ✅Forcing air or oxygen into the lungs when a patient has stopped
breathing or has inadequate breathing. Also called Positive Pressure Ventilation.
Apnea ✅No breathing, absence of breathing.
Bronchoconstriction ✅The contraction of smooth muscle that lines the bronchial
passages that results in a decreased internal diameter of the airway and increased
resistance to airflow.
Cyanosis ✅A bluish or purplish color of the skin due to insufficient oxygen levels in the
blood.
Diffusion ✅A process by which molecules move from an area of high concentration to
an area of low concentration.
Dyspnea ✅Difficult and labored breathing; shortness of breath.
Flail Chest ✅Fracture of two or more adjacent ribs in two or more places that allows for

without interference to the passage of air into and out of the body.
Pressure Regulator ✅A device connected to an oxygen cylinder to reduce pressure, so

3 ✅The pharynx is divided into how many regions?

A patent airway ✅What is required for air to move into and out of the lungs?
Upper Airway ✅Where does the air enter the body through the mouth and nose?
Posterior and inferior to the mouth and nasal passages ✅Where does air enter the
pharynx?
