the abdominal aorta bifurcates at
if you aspirate a peanut while upright: it enters
lower portion of right inferior lobe
if you aspirate a peanut while supine: it enters
superior portion of right inferior lobe
Right lung has.... lobes
Left lung has ... lobes
2 Lobes AND LINGULA
which lung is more common site for inhaled foreign body and why
Right lung because the right main stem bronchus is wider and more vertical than left
Lingula is homolog to
right middle lobe
right main stem bronchus vs left main stem bronchus
the right stem bronchus is wider and more vertical than the left
the relation of pulmonary artery and bronchus at each lung hilum is describeb by
bifurcation at L4
bifurcation at T4
bifurcation at C4

The inferior vena cava, which passes through the diaphragm at the level of T8 (8 letters in vena cava)
At what level does the esophagus perforate the diaphragm?
T10 (10 letters in [o]esophagus)
What three structures perforate the diaphragm at the level of T12?
The aorta (red), thoracic duct (white), and azygos vein (blue) (at T-1-2, it's the red, white, and blue—12 letters in aortic hiatus
Which tendon can be found on the inferior aspect of the diaphragm surrounding the caval and esophageal hiatuses?
The central tendon
What mnemonic can be used to recall the levels at which certain anatomic structures perforate the diaphragm?
I (IVC) ate (8) ten (10) eggs (esophagus) at (aorta) twelve (12)
