After 27 weeks, ____ of normal small bowel is increasingly observed.
Peristalsis
The ____ ____ of the colon help to defferentiate it from the small bowel.

Colon
The meconium within the lumen of the colon appears _____ relative to the fetal liver and in comparison with the bowel wall.
Hypoechoic

20
____ ____ may present as a total reversal of the thoracic and abdominal organs or as a partial reversal.

Partial Situs Inversus
True ascites is identified within the peritoneal recesses, whereas ____ is always confined to an anterior or anterolateral aspect of the fetal abdomen.
Pseudoascites
A bowel obstruction results in ____ bowel dilatation that is characteristically recognized as one or more tubular structures within the fetal abdomen.
Proximal
The most reliable criterion for diagnosing dilated bowel is the bowel ____, not the sonographic appearance.
Diameter
A congenital blockage of the esophagus resulting from faulty separation of the foregut into its respiratory and digestive components is ____ ____.
Esophageal Atresia
In reference to the diagnosis in question 6 (esophageal atresia), the sonographer may observe the ____ stomach and ____.
Absent, hyddramnios
Blockage of the jejunum and ileal bowel segments (jejunoileal atresia or stenosis) appears as multiple cystic structures ____ to the site of atresia within the fetal abdomen.
Proximal
A small-bowel disorder marked by the presence of thick meconium in the distal ileum is ____

Anorectal Atresia
Hyperechoic bowel is a(n) ____ impression of unusually echogenic bowel, typically seen during the 2nd trimester.
