Connect Quiz 15-Respiratory System – Flashcards

Which is not part of the conducting portion of the respiratory system? -Alveoli -Trachea -Larynx -Nasal cavity -Bronchi

Organize the items listed into the proper sequence of events for gas exchange. a: O2 is transported to cells by circulatory system b: O2 is drawn into the lungs during inhalation c: Cells use O2 and generate CO2 d: CO2 is exhaled e: The circulatory system transports CO2 to the lungs

Which is not a function of the respiratory system? -Sound reception -Gas exchange -Olfaction -Gas conditioning

Several things happen to inhaled air in a process called conditioning. Select the exception. -The air is cooled -The air is humidified -The air is cleansed -The air is moistened -The air becomes turbulent

The openings into the nasal cavity are the -Internal nares -Fauces -External nares -Paranasal sinuses -Inferior nasal conchae

Paranasal sinuses are not found within the -Sphenoid bone -Frontal bone -Ethmoid bone -Mandible -Maxilla.

What feature is used by both the respiratory and digestive systems? -Pharynx -Larynx -Nasal cavity -Paranasal sinuses -Esophagus

Into what region of the pharynx do auditory tubes open? -Oropharynx -Nasopharynx -Laryngopharynx

Food is normally prevented from entering the nasopharynx by the -Elevation of the epiglottis -Elevation of the soft palate -Depression of the hard palate -Closure of the nasal conchae -Constriction of the esophagus

What structure prevents food and drink from entering the trachea, conducts air, and produces sound? -Esophagus -Bronchi -Pharynx -Nasal cavity -Larynx

What structures actually produce sound? -Vestibular folds -Paranasal sinuses -Arytenoid cartilages -Vestibular ligaments -Vocal folds

What structure connects the larynx to the primary bronchi? -Trachea -Pharynx -Esophagus -Bronchioles -Alveolar ducts

Which statement is true regarding secondary bronchi? -The right lung has two secondary bronchi and the left lung has three secondary bronchi -The left lung has two secondary bronchi and the right lung has three secondary bronchi -Each lung has two secondary bronchi -Each lung has three secondary bronchi -Each lung has four secondary bronchi

The typical cell making up the alveolar wall is the -Alveolar type II cell -Alveolar type I cell -Alveolar macrophages -Dust cells -Septal cell

The alveolar cell that secretes pulmonary surfactant is the -Alveolar type II cell -Alveolar type I cell -Alveolar -Macrophages -Dust cells -Squamous alveolar cell

Phagocytic cells of the alveolus are the -Alveolar type II cells -Alveolar type I cells -Alveolar macrophages -Septal cells -Squamous alveolar cells

What prevents the trachea from collapsing? -The internal air pressure within the trachea -The surrounding muscles -The internal epithelium -The C-shaped cartilaginous rings -Nothing, it pulsates (expands and contracts) with each breath

The hilum of the lung -Is an indented area through which the bronchi, pulmonary vessels, lymphatic vessels, and nerves pass -Is the point of exit of exhaled air -Is the point of entrance for inhaled air -Is an elevated area through which the trachea, pulmonary vessels, and nerves pass -Serves to anchor all pulmonary structures to the mediastinum

The exchange of oxygen and carbon dioxide between the air and blood in the lungs is called -Ventilation -Systemic respiration -Internal respiration -External respiration -Cellular respiration

Which do not belong to the respiratory portion of the respiratory system? -Respiratory -Bronchioles -Alveolar ducts -Terminal bronchioles -Pulmonary alveoli -Alveolar sacs
