During the fetal period, the umbilical cord is the channel that connects the fetus to the mother, transmits oxygen and nutrients to the fetus, and then removes metabolic wastes from the body. It is an important safeguard mechanism for the fetus to thrive in the mother's body.

That's a boring question. From time immemorial. The human body has this organ. I can't say it's an organ. When we were inside our mom's womb. The belly button is connected to mom. When we are born. After the belly button is cut, it will fall to form a nest. This is the belly button. I don't know what it's for after that. Even if you know it's useless, will you fill it in?

The internal organs of the body can get some of their oxygen through the navel.
People in the fetal period rely on the umbilical cord to connect the fetus and the placenta, to meet the growth and development of the fetus needs nutrients, etc., after birth no longer need the mother's supply, so the umbilical cord is useless, leaving a ti is the belly button.
