Which of the following is part of the upper respiratory tract?
Trachea
Lungs
Nasal cavity
Alveoli
The primary function of the larynx is to:
Warm and moisten air
Filter debris from air
Prevent food from entering the trachea
Facilitate gas exchange
What is the function of the nasal conchae in the nasal cavity?
Gas exchange
Increase the surface area for air filtration
Conduct oxygen to the alveoli
Produce surfactant
Which cartilage forms the anterior portion of the larynx, commonly referred to as the "Adam's apple"?
Cricoid cartilage
Thyroid cartilage
Epiglottis
Arytenoid cartilage
What is the main function of the epiglottis?
Amplify sound
Protect the vocal cords
Close the glottis during swallowing
Assist in phonation
The trachea is lined with:
Simple squamous epithelium
Stratified squamous epithelium
Ciliated pseudostratified columnar epithelium
Transitional epithelium
The right lung is different from the left lung in that it:
Has two lobes
Is smaller to accommodate the heart
Has three lobes
Contains the cardiac notch
Which cells in the alveoli produce surfactant?
Type I alveolar cells
Type II alveolar cells
Alveolar macrophages
Goblet cells
What is the function of surfactant in the lungs?
Enhance oxygen binding to hemoglobin
Reduce surface tension to prevent alveolar collapse
Trap dust and pathogens
Facilitate mucus production
The pleura that directly covers the lungs is called the:
Parietal pleura
Visceral pleura
Pericardium
Pleural cavity
The region where blood vessels, nerves, and bronchi enter the lung is known as the:
Apex
Base
Hilum
Fissure
What structural characteristic of alveoli maximizes gas exchange?
Thick walls
Large surface area
Smooth muscle lining
Cuboidal epithelium
The primary function of the nasal hairs is to:
Detect odors
Humidify air
Filter large particles
Produce mucus
The pharynx connects the nasal cavity to the:
Esophagus and trachea
Trachea and larynx
Esophagus and stomach
Lungs and bronchi
The trachea is reinforced by which type of cartilage?
Elastic cartilage
Fibrocartilage
Hyaline cartilage
Calcified cartilage
Which structural feature distinguishes bronchioles from bronchi?
Bronchioles have cartilage rings
Bronchioles have smooth muscle and lack cartilage
Bronchioles contain hyaline cartilage
Bronchioles are part of the conducting zone only
The alveoli are lined by:
Simple cuboidal epithelium
Simple squamous epithelium
Pseudostratified columnar epithelium
Transitional epithelium
The medial surface of each lung contains the:
Apex
Fissures
Hilum
Pleural cavity
Which anatomical structure contains the vocal cords?
Pharynx
Trachea
Larynx
Bronchus
Part of the respiratory organ that is involved in filtration and humidification of air before entering the lungs is
larynx
trachea
pharynx
nasal cavity
