Answers
Bronchoconstriction
TIghtening of the bronchus due to the contraction of the smooth muscle.
Bronchodilation
Expansion of the airway in the bronchus.
Pleural Cavity
The space or cavity between the visceral and parietal layers of the lung.
Pleura
A protective layer or membrane covering the lungs.
Trachea
Allows air to pass to and from lungs
Pharynx
throat; passageway for food to the esophagus and air to the larynx
Larynx
voice box; passageway for air moving from pharynx to trachea; contains vocal cords
Bronchi
two short branches located at the lower end of the trachea that carry air into the lungs.
Diaphragm
A muscle that separates the chest cavity from the abdominal cavity and innervated by nerves.
Surfactant
A lubricant made in the lungs to keep the alveoli from collapsing during exhalation.
Atalactasis
Collapse of airways and small sections of the lung as a result of shallow breathing. The collapsing of the
lung during expansion.
Ventilation
The flow of air inside or outside of the alveoli.
Perfusion
, The flow of blood by the cardiopulmonary system into the alveolar capillaries where deoxygenated

Respirations
The amount of breaths per minute.
Red Blood Cells
Blood cells that carry oxygen from the lungs to the body cells.
Lung Compliance
The point to which a lung can expand in response to increased pressure within the alveoli
(interalveolar).
Airway Resistance
The pressure or opposition of the tissues in the airway to the flow of air.
Inspiratory Reserve Volume
Volume of air breathed in after a typical inspiration.
Tidal Volume
Volume of air inspired and expired with each breath.
Residual Volume
Volume of air remaining in the alveoli after expiration.
Forced Vital Capacity
Volume of air remaining in the lung after maximal inspiration.
Vital Capacity
Maximum volume of air that is expelled after maximal inspiration.
Total Lung Capacity
Volume of air remaining in the lung after maximal inspiration.
Pulmonary Circulation
The movement of blood from the heart to the lungs from the capillaries for gas exchange and back.
Tripod Position
Placement of the arms against the legs or examination table while seated.
Tactile Fremitus
