#1
Which organ is primarily responsible for the exchange of oxygen and carbon dioxide in the human body?
Lungs
ExplanationLungs facilitate gas exchange in the respiratory system.
#2
Which part of the brain is responsible for controlling the involuntary respiratory functions, such as breathing rate?
Medulla oblongata
ExplanationThe medulla oblongata controls involuntary respiratory functions.
#3
What is the term for the medical condition where there is an accumulation of fluid in the lungs, leading to difficulty breathing?
Pulmonary edema
ExplanationPulmonary edema is the accumulation of fluid in the lungs, causing difficulty in breathing.
#4
Which of the following is a chronic respiratory disorder characterized by the inflammation and irreversible narrowing of the bronchi and bronchioles?
Chronic bronchitis
ExplanationChronic bronchitis involves chronic inflammation and narrowing of bronchi and bronchioles.
#5
Which respiratory disorder is characterized by the formation of scar tissue in the lungs, leading to decreased lung function?
Pulmonary fibrosis
ExplanationPulmonary fibrosis involves the formation of scar tissue in the lungs, reducing lung function.
#6
What is the term for the medical condition where there is inflammation of the bronchial tubes, resulting in difficulty breathing?
Bronchitis
ExplanationBronchitis is characterized by inflammation of the bronchial tubes.
#7
Which respiratory disorder is characterized by the destruction of the alveoli and reduced elasticity of the lungs?
Emphysema
ExplanationEmphysema results in the destruction of alveoli and decreased lung elasticity.
#8
In the respiratory system, what is the primary function of the mucus produced in the airways?
Filtering dust particles
ExplanationMucus in the airways filters dust particles.
#9
Which gas, when present in elevated levels, can lead to respiratory problems and is a major component of air pollution?
Carbon monoxide
ExplanationElevated levels of carbon monoxide can cause respiratory problems and contribute to air pollution.
#10
Which of the following is NOT a function of the respiratory system?
Digestion of nutrients
ExplanationDigestion of nutrients is not a function of the respiratory system.
#11
What is the main function of the diaphragm in the respiratory system?
To aid in breathing
ExplanationThe diaphragm aids in the process of breathing.
#12
Which respiratory disorder is characterized by the sudden, severe restriction of airflow and difficulty in breathing?
Asthma attack
ExplanationAsthma attack involves sudden airflow restriction and difficulty in breathing.
#13
What is the purpose of the epiglottis in the respiratory system?
Preventing food from entering the trachea
ExplanationThe epiglottis prevents food from entering the trachea.
#14
Which respiratory disorder is characterized by the narrowing and inflammation of the airways, leading to wheezing and shortness of breath?
Bronchial asthma
ExplanationBronchial asthma involves narrowed and inflamed airways, causing wheezing and breathlessness.
#15
Which respiratory disorder is characterized by the inflammation and narrowing of the airways, triggered by specific allergens?
