Anatomy Flashcards
Upper respiratory tract
Nose, nasal cavity, pharynx
Lower respiratory tract
Larynx, trachea, bronchi, lungs
Function of epiglottis
Made of cartilage and will change position to close respiratory tract when swallowing
Where does the trachea separate into 2 bronchi
T4-T5
Which lung is larger
Right lung
Which lung is larger
Right lung
Right main bronchus characteristics
Wider and shorter
Which structures do not have cartilage
Bronchi and alveoli
Why is left lung smaller than right
Because heart on left side
Lobes of right lung
Upper lobe, middle lobe and inferior lobe.
Upper and middle lobe separated by horizontal fissure
Inferior lobe separated by middle and superior by oblique fissure
Lobes of left lung
Upper and lower lobe separated by horizontal fissure
What veins cross intersegmentally
Tributary veins
Which part is closest to the heart
Lingula
In hilum, position of bronchus
Posterior
In hilum, position of arteries
Anterior
In hilum, position of veins
Inferior
Origin of pulmonary ligament and function
Parietal pleura. Keeps the different elements in the root
What separates parietal pleura from ribs
Endothoracic fascia
Which are the most clinically relevant recesses
Costodiaphragmatic recesses
Innervation of respiratory tract
Pulmonary plexus
Parasympathetic fibers of pulmonary plexus come from
Vagus nerve
Where do sympathetic fibers synapse
Sympathetic chain
Parasympathetic fibers synapse at
Ganglia of respiratory trunk
Function of sympathetic fibers
Bronchodilation. Me persigue el oso
