Note:

Loops of the intestine temporarily move out of the crowded abdomen into the umbilical cord. This normal process is called "physiologic herniation." The rapidly growing liver fills the abdomen, temporarily leaving little room for other organs.

Label Key:

1. umbilical vein
2. base of umbilical cord
3. abdominal wall
4. loops of intestine
5. liver
All ages referenced to fertilization, not last menstrual period.
