The umbilical cord couldn’t have been spilling nutrients into the abdominal cavity — so there must be something connected on the other side!

Turns out there is.

No surprise to medical students, I’m sure, but interesting to me.

Among other things, the umbilical vein passes through the navel on its way to the liver. After birth, the outside part of the umbilical cord falls off, of course, but the inside part stays, and turns into this “round ligament of the liver,” and continues to hang around.
