Final answer:
Malrotation and volvulus are conditions that involve the small intestine. Ladd's bands can cause kinking of the duodenum and obstruction. During gut development, the intestines should rotate 270 degrees counterclockwise around the SMA.
Step-by-step explanation:
Malrotation and volvulus are conditions that involve the small intestine. Malrotation refers to abnormal development and fixation of the intestines during fetal development, while volvulus refers to the twisting of the intestines on itself. Ladd's bands are fibrous bands that can kink the duodenum and cause obstruction. Another important aspect of gut development is the rotation of the intestines, which normally occurs 270 degrees counterclockwise around the superior mesenteric artery (SMA).
