Respiratory anatomy Flashcards
What is A?
Sphenoidal sinus
What is B ?
Semilunar hiatus
What is C ?
Opening for posterior ethmoidal sinuses
What is D?
Frontal sinus
What is E?
Inferior concha
What is F ?
Choanae (posterior nasal aperture)
What is G ?
Soft palate
What is H ?
Pharyngotympanic tube opening
What is I?
Opening for Maxillary sinus.
On the image opposite, what is located at the area marked by the blue circle?
Olfactory area
What are the functions of the conchae?
Increase surface area - humidify
Keep airways open
What are the functions of the paranasal sinuses?
Function unconfirmed – many theories.
May be to lighten skull, role in immune function, spaces for voice to resonate
Clinical – Used in immune response
If the larynx fails to close and food or liquid are able to pass through, what condition could result?
Aspiration pneumonia – food/drink causes infection within the lungs.
Why is the cartilage of the trachea C-shaped?
Allows for expansion of oesophagus posteriorly.
Airway is always open.
If a small object is aspirated and becomes lodged in the lung, where would it lodge and why?
Right main bronchus – wider and more vertical than left
Where does gas exchange occur?
Respiratory bronchioles and alveoli
The right lung is generally shorted and wider than the left lung, why do you think that is?
Diaphragm is higher on right due to liver.
Each lung is divided into 10 bronchopulmonary segments, meaning they are functionally independent. How can this be helpful clinically?
Areas can be removed without impacting the whole structure – Functionally independent
