HSS 3305 MODULE 7 PRACTICE EXAM
QUESTIONS WITH VERIFIED ANSWERS
What is the highest mountain on Earth?
Mount Everest, known in Nepali as Sagarmatha and in Tibetan as Chomolungma.
What major achievement did Edmund Hillary and Tenzing Norgay accomplish?
They became the first people to reach the summit of Mount Everest on May 29, 1953.
What happens to air pressure at higher altitudes?
Air pressure is substantially lower, making oxygen less accessible.
What physiological changes occur in the body when acclimating to high altitudes?
The lungs become larger, and the body produces more red blood cells and capillaries.
What unique adaptation do Sherpas have regarding oxygen utilization?
Sherpas' muscle cells' mitochondria can convert more oxygen into energy, conserving muscle
energy levels at high altitudes.
What are the four processes involved in respiration?
1. Pulmonary ventilation 2. External respiration 3. Transport of respiratory gases 4. Internal
respiration.
What is the primary function of the respiratory system?
To supply the body with oxygen (O2) and dispose of carbon dioxide (CO2).
What are the two divisions of respiratory system organs?
1. Conducting zone 2. Respiratory zone.
What is the role of the conducting zone in the respiratory system?
It conveys air and filters, humidifies, and warms incoming air.
Where does gas exchange occur in the respiratory system?
In the respiratory zone, specifically at the alveoli.
What are the main organs of the respiratory system?
Nose, nasal cavity, paranasal sinuses, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli.
What is the function of the nasal cavity?
It moistens and warms air, filters inhaled air, and houses olfactory receptors.
,What are the two types of mucous membranes in the nasal cavity?
1. Olfactory mucosa 2. Respiratory mucosa.
What is the function of olfactory mucosa?
It houses olfactory (smell) receptors near the roof of the nasal cavity.
What is the role of respiratory mucosa?
It lines the nasal cavity and moves contaminated mucus posteriorly to the pharynx.
What is sinusitis?
Sinusitis is an inflammation of the paranasal sinuses, usually due to a viral or bacterial infection.
What are common causes of acute sinusitis?
Viral infections (like rhinovirus and influenza) and bacterial infections (like Streptococcus
pneumoniae and Haemophilus influenzae).
What symptoms are associated with sinusitis?
Pain and pressure over the affected sinuses.
What are paranasal sinuses?
Hollow, air-filled spaces named for the skull bone that each occupies, lined with mucous
membrane that drains into the nasal cavity.
What is the significance of nasal conchae?
They filter, heat, and moisten incoming air and reclaim moisture and heat during exhalation.
What is the anatomical location of the frontal sinus?
Within the frontal bone.
What is the anatomical location of the maxillary sinus?
Within the maxillary bones.
What is the anatomical location of the sphenoid sinus?
Within the sphenoid bone.
What is the anatomical location of the ethmoidal sinus?
Within the ethmoid bone.
What is a dental implant in the context of the ethmoid sinus case study?
A foreign body found in the left ethmoid sinus of a patient with recurrent sinusitis.
What imaging technique was used to identify the dental implant in the ethmoid sinus?
, Computed tomography (CT) scan.
What is the ostiomeatal complex?
An area in the nasal cavity where the sinuses drain, significant in sinusitis cases.
What is the function of the larynx?
Voice production, provides an open airway, routes air and food into the proper channels.
What are the three sections of the pharynx?
Nasopharynx, Oropharynx, Laryngopharynx.
What is the location of the nasopharynx?
Superior to the point where food enters; only an air passageway.
What is the role of the uvula during swallowing?
It reflects superiorly to close off the nasopharynx.
What does the oropharynx extend from?
From the soft palate to the epiglottis.
What is the laryngopharynx a passageway for?
Both food and air; it is continuous with the esophagus and larynx.
What are the nine cartilages of the larynx?
Three unpaired: Thyroid, Cricoid, Epiglottis; Three paired: Arytenoid, Corniculate, Cuneiform.
What is the laryngeal prominence commonly known as?
Adam's apple.
What is the cricoid cartilage?
Ring-like cartilage that forms the inferior wall of the larynx, attached to the top of the trachea.
What is the function of the epiglottis during swallowing?
It moves down to form a lid over the glottis, closing it off.
What is epiglottitis?
Inflammation and swelling of the epiglottis, often caused by infection or throat injury.
What are vocal folds also known as?
True vocal cords.
What is the role of vestibular folds?
