Respiratory Care and Pulmonary Function Quiz

Respiratory system primarily facilitates gas exchange.

Alveoli facilitate gas exchange between air and blood.

Exhalation is the expulsion of air from the lungs.

Carbon dioxide is a byproduct of cellular respiration and a major atmospheric gas.

Pharynx is part of the upper respiratory tract.

Gas exchange involves removal of CO2 and intake of O2.

Tidal volume is the amount of air moved in normal breathing.

Alveoli are part of the respiratory zone, not the conducting zone.

Larynx is the organ containing the vocal cords.

Asthma causes inflammation in the airways, leading to breathing difficulties.

Pneumothorax involves collapsed airways, impeding exhalation.

Surfactant ensures alveoli remain open for gas exchange.

Gas exchange between lungs and blood occurs through diffusion.

Perfusion involves exchange of gases between blood and tissues.

Chronic bronchitis often presents with a persistent cough.

Pleural effusion results in fluid accumulation around the lungs.

Emphysema involves damage and enlargement of lung air sacs.

Asthma involves inflamed airways, leading to constriction and mucus.

Diaphragm contracts during inspiration, increasing lung volume.

Oxygen binds to hemoglobin for transport in red blood cells.

Vital capacity is the maximum breath volume.

Abdominal muscles contract during forced expiration.

Pneumothorax involves air accumulation in the pleural cavity.

Bronchitis involves airway inflammation, mucus, and cough.

FVC assesses the maximum exhale capacity after a deep inhalation.
