Respiratory Care Processes Quiz

Respiratory system primarily facilitates gas exchange, not digestion.

The trachea is part of the lower respiratory tract, not the upper.

The pharynx is a common passage for both air and food in the respiratory and digestive systems.

The nasal cavity is not responsible for surfactant production, which occurs in the lungs.

The epiglottis acts as a flap, preventing food from entering the trachea while swallowing.

Oxygen and carbon dioxide exchange occurs through diffusion across membranes.

Asthma involves airway inflammation and constriction, causing breathing difficulties.

Diaphragm and intercostal muscles work together to expand the thoracic cavity during inhalation.

Arterial blood gas analysis measures oxygen and carbon dioxide levels, indicating lung function.

Cilia are hair-like structures that help move mucus and particles out of the respiratory tract.

Cigarette smoking is a major risk factor for developing COPD.

Surfactant reduces surface tension, preventing alveoli collapse and aiding in lung expansion.

The medulla oblongata controls involuntary functions, including breathing.

Vital capacity is the maximum air volume expelled after a full inhalation, a measure of lung function.

Pulmonary fibrosis involves gradual lung tissue scarring, compromising respiratory function.

Respiration involves the exchange of gases between blood and body tissues for cellular function.

Atelectasis involves the partial or complete collapse of lung sections.
