THIS IS A COMPLETE RING OF HYALINE CARTILAGE THAT FORMS THE INFERIOR WALL OF THE LARYNX.
Cricoid
The layer of the pluera in direct contact with the lung is called the_______…?
Visceral pluera
THESE ARE THE INFERIOR FOLDS WITHIN THE LARYNX THAT VIBRATE TO PRODUCE SOUND (PHONATION)
Vocal folds
Each lobe of a lung receives air from….?
Secondary bronchi
OXYGEN ENTERS THE BLOODSTREAM AND CARBON DIOXIDE EXITS THE BLOODSTREAM PRIMARILY AT ….?
ALVEOLI AND PULMONARY CAPILLARIES
THE _______ CARTILAGE IS THE ONLY CARTILAGE THAT COMPLETELY SURROUNDS THE RESPIRATORY TRACT
Cricoid
DURING INHALATION AIR IN THE LOBAR BRONCHI MOVES INTO THE…?
SEGMENTAL BRONCHI
_______BRING OXYGENATED BLOOD AWAY FROM PULMONARY CAPILLARIES
PULMONARY VENULES
THESE CELLS SECRETE ALVEOLAR FLUID CONTAINING SURFACTANT, WHICH KEEPS THE SURFACE MOIST AND LOWERS SURFACE TENSION.
Type 2 alveolar cells
Which of the following is a region of the respiratory zone?
Alveolar duct
Nasal conchae are…?
-PROJECTIONS WITHIN THE NASAL CAVITY THAT INCREASE THE SURFACE AREA FOR CONDITIONING OF THE AIR THAT ENTERS
Which of the following is a region of the conduction zone ?
Trachea
THESE ARE THE SUPERIOR FOLDS WITHIN THE LARYNX THAT FUNCTION IN HOLDING THE BREATH AGAINST PRESSURE IN THE THORACIC CAVITY
-VESTIBULAR FOLDS
The opening to the Eustachian tube is located within the
Nasopharynx

Internal respiration is…..?
THE EXCHANGE OF OXYGEN AND CARBON DIOXIDE BETWEEN SYSTEMIC CAPILLARIES AND TISSUE CELLS
As blood carbon dioxide levels decline, respiratory rate____________?
Decreases
External respiration is….?
THE EXCHANGE OF OXYGEN AND CARBON DIOXIDE BETWEEN ALVEOLI AND PULMONARY CAPILLARIES .
IF THE BODY INCREASES AEROBIC CELLULAR RESPIRATION WITHOUT AN INCREASE IN VENTILATION……

False
The amount of air moving in and out during forced breathing is called…?
Vital capacity
The amount of air remaining in the lungs after forced exhalation occurs is called….?
Residual volume
What is the exchange of air between the atmosphere and the lungs…?
Pulmonary ventilation

As PH decreases, the affinity of hemoglobin for oxygen ___________.
Decreases
During external(pulmonary) respiration carbon dioxide moves from ____________ to _____________.
Pulmonary capillaries ; alveolar air
Carbonic acid increases the PH of tissue.
TRUE OR FALSE?
