Anatomy 15 - Respiratory System Flashcards
What does the respiratory system allow for
Inspiration, gas exchange and expiration
What does it take in and give out
It takes in oxygen and gives out carbon dioxide
What is the respiratory tract composed of
The nasal canal, hard palate, choana, soft palate, nostrils, epiglottis, glottis, phatynx, larynx, oesophagus, trachea, lung, pleura cavity and bronchi
Functions of the nasal cavity
To filter, warm and moisten the air
What lies within the nasal cavity
The concha
What are the three concha
The superior, middle and inferior concha
What are the concha
Folds of tissue on the lateral wall of the nasal fossa
What are the concha covered in
Mucous
What are the functions of the concha
To create turbulance with the air passing through and warm the blood
How is the air in the nasal cavity warmed
Through capillaries in the concha being close to the surface
What are the narrow passages between the concha known as
Meatuses
What are the para-nasal sinuses
Air filled spaces within the skull
Functions of the para-nasal sinuses
To lighten the skull and produce mucous
What do the nasal cavity and para-nasal sinuses allow for in relation to sound production
Resonance
What are the three sections of the pharynx
The nasopharyns, oropharynx and the laryngopharynx
What is the larynx
The vocal box
How does the larynx produced sound
Through vibrations of the vocal folds

Anteriorly
What connects the edges of the cartilage within the trachea
Small muscles
When the trachea bifurcates what does it give
The left and right main bronchi
What are the vital organs of respiration
The lungs
Main function of the lungs
To oxygenate blood
What are the two pleura of the lungs
Parietal and visceral
What does the parietal pleura line
The pulmonary cavity
What are the different sections of the parietal cavity
Cervical, costal, diaphragmatic and mediastinal
What does the visceral pleura cover
The surface of the lungs
WHat is the pulmonary ligament
The sleeve of pleura that hangs down below the lung root
