Respiratory System Quiz

Which part of the respiratory system is responsible for filtering, warming, and moistening air?

• Trachea

• Nasal cavity

• Bronchioles

• Larynx

What is the function of the pharynx in the respiratory system?

• Filtering air

• Gas exchange between air and blood

• Conducting air into the lungs

• Resonating chamber for speech sounds

Which structure in the respiratory system is composed of nine pieces of cartilage?

• Trachea

• Larynx

• Bronchi

• Alveoli

What is the function of surfactant in the alveoli?

• Remove fine dust particles

• Secrete alveolar fluid

• Produce reticular and elastic fibers

• Reduce surface tension of alveolar fluid

Which part of the respiratory system is responsible for maintaining patency by preventing collapse of the air passageways?

• Smooth muscle in the bronchioles

• Fibroblasts in the alveolar wall

• Surfactant in the alveoli

• C-shaped rings of cartilage in the trachea

What is the primary function of the conducting zone in the respiratory system?

• Conduct air into the lungs

• Filter, warm, and moisten air

• Detect olfactory stimuli

• Gas exchange between air and blood

Which part of the respiratory system is lined with ciliated pseudostratified columnar epithelium with numerous goblet cells?

• Nasal cavity

• Pharynx

• Larynx

• Trachea

What is the role of the paranasal sinuses in the respiratory system?

• Serve as resonating chambers for sound

• Drain tears

• Produce mucus

• Exchange air with the auditory tubes

Which structure in the respiratory system is responsible for equalizing air pressure between the middle ear and the atmosphere?

• Oropharynx

• Nasal vestibule

• Nasopharynx

• Laryngopharynx

What is the function of the bronchioles in the respiratory system?

• Produce surfactant

• Branch into terminal bronchioles

• Remove fine dust particles

• Increase surface area in the internal nose
