Block 2 - Embryology of Lungs, Diaphragm, Heart Flashcards
foregut portion that results in the trachea and bronchii
diverticulum
most of the cartilage of trachea, and things that we can touch of the respiratory system is made of blank
mesoderm
forms inside of respiratory system
endoderm
esophagus and trachea used to be blank
one
most frequent anomaly in esophagus and trachea
superior esophagus ends in a pouch, inferior part of esophagus attached to trachea
percent of lung that develops after birth
90%
pneumocytes produce blank which keeps the lung expanded when taking a breath
surfactant
four things that form the diaphragm
septum transversum, pleuroperitoneal membrane, dorsal esophageal mesentery, body wall
forms the central tendon of diaphragm
septum transversum
most common place of diaphragmatic herniation
pleuroperitoneal membrane
forms the crura of the diaphragm
dorsal esophageal mesentery
forms peripheral muscular part of diaphragm
body wall
aka visceral
splanchnic
formation of heart is accomplished by blank mesoderm
lateral plate
blank are actually superior in the development of the heart before rotation
ventricles
separation of atria during development is accomplished by blank which forms the blank
endocardial cushion, septum primum
the blank is seen due to a hole of the septum secundum because you can see the septum primum which actually makes up this
foramen ovale
this forms av valves, leaflets, chordae tendonae
endocardial cushion
most defects in hearts of the patients are due to blank defects
ventricular septum
most defects occur in blank not blank
membrane, muscle
tetraology of fallot
OVEN
OVEN means this
overriding aorta, ventricular septal defect, pulmonary stEEEEEnosis, right veNNNNtricular hypertrophy
fourth arch on left forms bank
arch of aorta
fourth arch on right forms blank
right subclavian
recurrent laryngeal nerve is only seen on the blank side of the thorax
left
ductus arteriosum becomes blank after birth
ligamentum arteriosum
