Esophagus
Trachea
What is the primary function of the pharynx?

Epiglottis
Trachea
What structure is referred to as the 'Adam's Apple'?
Vocal cords

Epiglottis
Tongue
What is the trachea composed of?
Solid bands of bone
C-shaped rings of hyaline cartilage
Flexible muscle tissue
Circular bands of fibrous tissue
Why are the C-shaped rings of hyaline cartilage important for the trachea?
They help the trachea produce mucus
They keep the trachea open for the passage of oxygen into the lungs
They allow the trachea to expand and contract during breathing
They prevent the trachea from collapsing during exhalation
Which structure does the trachea connect to at its lower end?
The alveoli
The diaphragm
The bronchi
The nasal cavity
What is the function of the diaphragm in the lower respiratory system?
It divides the trachea into the right and left bronchi.
It separates the abdomen from the chest and allows inhalation and exhalation.
It lines the thoracic cavity.
It is a space found in the midline of the thoracic cavity.
What are alveoli in the lower respiratory system?
Cone-shaped organs that fill the thoracic cavity.
Globular air sacs found at the end of bronchioles.
Tubes that subdivide into smaller bronchioles.
The lining of the thoracic cavity.
What are the bronchi in the lower respiratory system?
They are cone-shaped organs that fill the thoracic cavity.
They are globular air sacs found at the end of bronchioles.
They are located at the lower end of the trachea and divide into the right and left bronchus.
They are the lining of the thoracic cavity.
What are the bronchial tubes responsible for in the lower respiratory system?
They divide the trachea into the right and left bronchus.
They enter the lungs and subdivide into bronchioles.
They are cone-shaped organs that fill the thoracic cavity.
They are globular air sacs found at the end of bronchioles.
What is the process called when oxygen is inhaled and carbon dioxide is exhaled during breathing?
External respiration
Internal respiration
Cellular respiration
Photosynthesis
What happens to the diaphragm during inhalation?
It relaxes and moves upward.
It contracts and pulls down.
It remains stationary.
It expands and moves upward.
How many times does a normal adult breathe per minute?
5-10 times
12-20 times
25-30 times
30-40 times
How do chemical factors compare to neural factors in the regulation of respiration?
Chemical factors regulate voluntary breathing, while neural factors regulate involuntary breathing.
Neural factors control the diaphragm, while chemical factors detect changes in blood gases.
Chemical factors detect changes in blood gases, while neural factors regulate the rate and depth of breathing.
Neural factors detect changes in blood gases, while chemical factors control the diaphragm.
What is the term for a sleep disorder in which breathing repeatedly stops and starts?
Tachypnea
Apnea
Cheyne-Stokes
Bradypnea
Which of the following best describes anaphylaxis?
A mild allergic reaction causing skin irritation
A serious allergic reaction that can be life-threatening
A condition caused by a foreign object in the throat
A bacterial infection in the respiratory system
What happens to the airway during severe asthma?
The airway becomes completely blocked.
The airway becomes inflamed, severely tightened, and produces excess mucus.
The airway becomes larger to allow more airflow.
The airway remains unaffected.
What does COPD stand for?
Chronic Obstructive Pulmonary Disorder
Chronic Obstructive Pulmonary Disease
Chronic Obstruction Pulmonary Dysfunction
Chronic Obstruction Pulmonary Disease
What is the common cold classified as?

They cause immediate symptoms
The (a) is composed of the chambers of the internal nose that function
as a part of the upper respiratory system.
The (a) is the most posterior part of the pharynx. It is shared by the
respiratory system and the digestive system. The upper respiratory and upper digestive
tracts diverge right after this structure. The front of this structure merges with the triangular
entrance of the larynx.
The (a) conveys air between the upper and lower
respiratory structures.
The (a) is a portion of the pharynx that begins at the rear of the nasal
cavity and functions as an airway in the upper respiratory system. Its cavity always stays open,
unlike the other parts of the pharynx.
The (a) are two organs that are responsible for gas exchange.
The (a) are the major airways of the lower respiratory system.
The (a) are the main sites of gas exchange, where oxygen is brought into the bloodstream and carbon dioxide is removed.
The (a) is a portion of the pharynx that is shared by the respiratory system and the digestive system. It functions as an airway in the upper respiratory system.
