Anatomy Flashcards
what Contains hyaline cartilage, and is surrounded by the arch of the azygous vein?
right main bronchus
what carries oxygenated blood, and are sited inferoposteriorly within the lung root?
pulmonary vein
what arise from the anterior surface of descending aorta?
bronchial arteries
where is the lung base auscultated?
T11 vertebra
what is the anatomical site of horizontal fissure?
right 4th rib
what is the level of the oblique fissure posteriorly
T3 vertebra
what is the site used in decompressing a tension pneumothorax?
2nd intercostal space
what is the site of the oblique fissure anteriorly?
rib 6
what is the stage of lung maturation that takes place between 16-28 weeks’ gestation. It sees the branching of terminal bronchioles into respiratory bronchioles and finally alveolar ducts?
canalicular
what is the germ layer that forms the lining of the trachea and bronchial tree?
endoderm
what is the structure that develops on the anterior foregut and is the first respiratory structure to develop?
respiratory diverticulum
what is the stage of lung maturation that takes place between 6-16 weeks’ gestation. It involves the development of multiple branches of the bronchial tree down to the level of the terminal bronchioles?
Pseudoglandular
what is the germ layer that forms the cartilage and smooth muscle in the thorax?
visceral mesoderm
what is the stage of lung maturation that takes place between 28-36 weeks’ gestation. The terminal sacs form, and capillaries come into close contact with the alveoli ready for gas exchange?
saccular
what is the stage of lung maturation that takes place between 36 weeks’ gestation and early childhood and involves further maturation of the alveoli?
alveolar
