After some recent bouts of navel-gazing, it occurred to me that I had no idea what was on the other side of the navel. 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.

    Hey hey!!!… thanks for sharing this stuff.
    I am on the verge of becoming a father and was wondering, just like other nuts like me :) , what’s left on the side of the navel after the umbilical cord detaches.
    Could you help me with understanding what happens to rest of the wiring in the tummy? Does that also remain “hanging around” like the round ligament of the liver???
