ATI GAS EXCHANGE AND OXYGENATION TOP
test questions and CORRECT Answers
Bronchoconstriction - CORRECT ANSWERS Tightening of the bronchus due to the contraction
of the smooth muscle
Bronchodilator - CORRECT ANSWERS Expansion of the airway in the bronchus
Pleural cavity - CORRECT ANSWERS Their space or cavity between the visceral and parietal
layers of the lung
Pleura - CORRECT ANSWERS A protective layer or membrane covering the lungs
The diaphragm is controlled by the... - CORRECT ANSWERS Autonomic nervous system
Surfactant - CORRECT ANSWERS Lubrication made in the lungs to keep the alveoli from
collapsing during exhalation
Ventilation - CORRECT ANSWERS Flow of air inside or outside of the alveoli
Perfusion - CORRECT ANSWERS Flow of blood by the cardiopulmonary system into the alveolar
capillaries where deoxygenated blood is exchanged for oxygenated blood in the heart and delivered
to the rest of the body
Lung compliance - CORRECT ANSWERS The point to which a lung can expand in response to
increased pressure within the alveoli (Interalveolar)
Airway resistance - CORRECT ANSWERS The pressure of opposition of the tissues in the airway
to the flow of air
Inspiration reserve volume - CORRECT ANSWERS Volume of air breathed in after a typical
inspiration
, Expiratory reserve volume - CORRECT ANSWERS Air expelled after each breath
Tidal volume - CORRECT ANSWERS Volume of air inspired and expired with each breath
Residual volume - CORRECT ANSWERS Volume of air remaining in the alveoli after expiration
Forced vital capacity - CORRECT ANSWERS The amount of air that is expelled from the lungs in
1 second during forced expiration ( the maximum amount of air you can forcibly exhale from your
lungs after fully inhaling)
Vital capacity - CORRECT ANSWERS Maximum volume of air that is expelled after maximal
inspiration (not in a forced manner)
Total lung capacity - CORRECT ANSWERS Volume of air remaining in the lung after maximal
inspiration
Pulmonary circulation - CORRECT ANSWERS The movement of blood from the heart to the
lungs from the capillaries for gas exchange and back
Diastole - CORRECT ANSWERS The relaxation phase of the cardiac cycle where the heart
muscle is relaxed and the chambers of the heart fill with blood
Systole - CORRECT ANSWERS The contraction phase of the cardiac cycle when the mitral and
tricuspid valves close and blood is ejected into the aorta and pulmonary arteries
Cardiac output - CORRECT ANSWERS The volume of blood ejected by the heart ventricles in
one minute
Stroke volume - CORRECT ANSWERS Volume of blood ejected by the left ventricle during one
contraction
Preload - CORRECT ANSWERS The blood remaining in the left ventricle at the end of diastole
prior to the next contraction
