Respiratory System Notes
What is the first step of the respiratory tract?-✔✔ Nose (nares)
What is the function of the conchae in the nasal cavity?-✔✔ Modifies,
warms, and filters incoming air
What is the function of the mucociliary system in the respiratory tract?-✔✔
Protects the respiratory tract from infections and debris
Where are the tonsils located in the respiratory system?-✔✔ Around the
transition between the nasal cavity and pharynx (throat)
What is the primary role of the tonsils in the immune system?-✔✔ Help
protect the body from foreign threats from both nasal and oral pathways
What can severe inflammation of the tonsils lead to?-✔✔ Airway
blockages
What is the role of the epiglottis in the larynx?-✔✔ Closing the airway
when swallowing to prevent aspiration
What does the term "Adam's Apple" refer to in the respiratory system?-✔✔
Thyroid cartilage
What is the function of the vocal cords in the larynx?-✔✔ Production of
sound
What is the main function of the trachea in the respiratory system?-✔✔
Connecting the larynx to the bronchi
What separates the left and right main bronchi?-✔✔ Bifurcation of the
trachea
,What is the function of the main bronchi in the respiratory system?-✔✔
Primary branches off the trachea that serve as a "highway" for air
What is the function of secondary and tertiary bronchi in the respiratory
system?-✔✔ They are "highway exits" branching off the main bronchi
What is the primary function of bronchioles in the respiratory system?-✔✔
To serve as "individual streets" that feed into alveolar sacs
What is the function of alveoli in the respiratory system?-✔✔ Responsible
for gas exchange (respiration)
What is the purpose of alveolar mucous glands in the alveoli?-✔✔ They
secrete mucus to help lubricate the alveoli
What is the function of elastic fibers covering the alveolar sacs?-✔✔ To
promote smooth expansion and recoil during inspiration and expiration
What type of gas exchange occurs in the alveoli?-✔✔ Oxygen diffuses
from alveoli into the bloodstream, while carbon dioxide diffuses from the
bloodstream into alveoli.
What are the two layers of the pleura in the respiratory system?-✔✔
Parietal pleura and visceral pleura
What is the purpose of the pleural space in the respiratory system?-✔✔ It
is a fluid-filled space that minimizes friction during lung expansion and
contraction.
What is the main muscle responsible for respiration in the human
body?-✔✔ Diaphragm
What is the primary effect of the diaphragm's contraction on the
lungs?-✔✔ Expansion of the lungs, allowing air to enter.
, What is the difference in the number of lobes between the right and left
lungs?-✔✔ The right lung has three lobes (upper, middle, lower), while
the left lung has two lobes (upper, lower).
What is the purpose of the cardiac notch in the left lung?-✔✔ It provides
space for the heart (♥).
What is the significance of lung volumes and capacities in respiratory
assessment?-✔✔ They provide information about a person's lung function
and capacity.
What does the term "Vital Capacity (VC)" represent in lung
measurements?-✔✔ The amount of air that can either be inhaled or
exhaled.
What is the primary role of residual volume (RV) in the lungs?-✔✔
Volume of air left inside the lungs during complete inhalation or exhalation.
What is the total lung capacity (TLC) in the respiratory system?-✔✔ The
volume of air that the lungs can hold, which is the sum of vital capacity and
residual volume.
What is the normal range for tidal volume (TV) during regular
breathing?-✔✔ Roughly 500cc of air.
What is the term for normal depth and rate of breathing?-✔✔ Eupnea
What condition is characterized by fast, shallow respirations?-✔✔
Tachypnea
What respiratory pattern involves slow respirations?-✔✔ Bradypnea
What is the term for regular, rapid, and deep respirations?-✔✔ Kussmaul
What is the first step of the respiratory tract?-✔✔ Nose (nares)
