#1
Which of the following is NOT a function of the respiratory system?
Production of hormones
ExplanationRespiratory system primarily facilitates gas exchange.
#2
What is the primary function of alveoli in the respiratory system?
To exchange oxygen and carbon dioxide with the blood
ExplanationAlveoli facilitate gas exchange between air and blood.
#3
What is the term for the process of breathing out air from the lungs?
Exhalation
ExplanationExhalation is the expulsion of air from the lungs.
#4
Which gas makes up the majority of the Earth's atmosphere and is also a waste product of cellular respiration?
Carbon dioxide
ExplanationCarbon dioxide is a byproduct of cellular respiration and a major atmospheric gas.
#5
Which of the following structures is NOT part of the lower respiratory tract?
Pharynx
ExplanationPharynx is part of the upper respiratory tract.
#6
What is the term for the process of removing carbon dioxide from the blood and replacing it with oxygen?
Gas exchange
ExplanationGas exchange involves removal of CO2 and intake of O2.
#7
What is the medical term for the voice box?
Larynx
ExplanationLarynx is the organ containing the vocal cords.
#8
What condition is characterized by the inflammation of the bronchial tubes, resulting in coughing, wheezing, and difficulty breathing?
Asthma
ExplanationAsthma causes inflammation in the airways, leading to breathing difficulties.
#9
Which respiratory disorder is characterized by the collapse of small airways in the lungs, making it difficult to exhale air?
Pneumothorax
ExplanationPneumothorax involves collapsed airways, impeding exhalation.
#10
What is the role of surfactant in the lungs?
To prevent alveolar collapse
ExplanationSurfactant ensures alveoli remain open for gas exchange.
#11
What is the term for the process of gas exchange between the lungs and the blood?
Diffusion
ExplanationGas exchange between lungs and blood occurs through diffusion.
#12
What is the term for the process of gas exchange between the blood and body tissues?
Perfusion
ExplanationPerfusion involves exchange of gases between blood and tissues.
#13
Which pulmonary function test measures the maximum amount of air a person can exhale forcefully after a deep breath?
Forced vital capacity (FVC)
ExplanationFVC assesses the maximum exhale capacity after a deep inhalation.
