#1
Which structure is responsible for gas exchange in the lungs?
Alveoli
ExplanationAlveoli are small, air-filled sacs in the lungs where oxygen and carbon dioxide exchange occurs.
#2
What is the medical term for difficulty breathing?
Dyspnea
ExplanationDyspnea is the medical term used to describe difficulty or discomfort in breathing.
#3
What is the term for the process of moving air into and out of the lungs?
Ventilation
ExplanationVentilation is the process of moving air into and out of the lungs, facilitating gas exchange.
#4
Which respiratory disorder is characterized by inflammation of the bronchial tubes, leading to coughing, mucus production, and difficulty breathing?
Bronchitis
ExplanationBronchitis is inflammation of the bronchial tubes, causing symptoms like coughing and difficulty breathing.
#5
What is the primary muscle responsible for inspiration at rest?
Diaphragm
ExplanationThe diaphragm is the primary muscle responsible for inspiration at rest, contracting to expand the thoracic cavity and draw in air.
#6
Which of the following is NOT a function of the respiratory system?
Transport of nutrients
ExplanationThe respiratory system is not responsible for the transport of nutrients; its primary functions include gas exchange and oxygenation of blood.
#7
Which of the following respiratory disorders is characterized by inflammation and narrowing of the airways, leading to wheezing and difficulty breathing?
Asthma
ExplanationAsthma is a respiratory disorder involving airway inflammation, leading to symptoms like wheezing and breathlessness.
#8
Which respiratory parameter represents the volume of air inspired or expired with each breath during normal breathing?
Tidal volume
ExplanationTidal volume is the amount of air breathed in or out with each normal breath during quiet breathing.
#9
Which respiratory disorder is characterized by the permanent enlargement of airspaces distal to the terminal bronchioles, accompanied by destruction of alveolar walls?
Emphysema
ExplanationEmphysema is a respiratory disorder involving permanent enlargement of airspaces and destruction of alveolar walls.
#10
What is the term for the process by which oxygen is transported from the lungs to the tissues and carbon dioxide is transported from the tissues to the lungs?
Respiration
ExplanationRespiration is the process of exchanging oxygen and carbon dioxide between the lungs and the tissues.
#11
Which respiratory parameter represents the maximum volume of air that can be forcefully exhaled after a maximum inhalation?
Expiratory reserve volume
ExplanationExpiratory reserve volume is the maximum amount of air that can be forcefully exhaled after a deep inhalation.
#12
Which of the following respiratory disorders is characterized by progressive scarring of lung tissue, leading to stiffening of the lungs and impaired oxygenation?
Pulmonary fibrosis
ExplanationPulmonary fibrosis involves progressive scarring of lung tissue, leading to stiffening of the lungs and impaired oxygenation.
#13
What is the name of the condition characterized by episodes of interrupted breathing during sleep?
Sleep apnea
ExplanationSleep apnea is a condition marked by brief interruptions in breathing during sleep, often causing awakening.
