In placental mammals, the umbilical cord is a tube that connects a developing embryo or fetus to its placenta. It contains one or two major veins, buried within Wharton's jelly, for the exchange of nutrient- and oxygen-rich blood between the embryo and placenta.
In the third stage of labour, the uterus expels the placenta along with the cord from the mother's body. After the cord is separated from the placenta, the umbilical stub on the newborn's belly dries and comes off after a few days. It leaves only a small scar (the umbilicus) behind.
In humans, the cord is clamped or cut after birth. The umbilical cord is made of Wharton's jelly, not ordinary skin and connective tissue. There are no nerves, so cutting it is not painful. There is ordinarily no significant loss of either infant or maternal blood while cutting the cord. In some cultures the umbilical cord is cut by the father of the baby. Lotus Birth is a practice of leaving the cord uncut after birth so that the baby is left attached to its placenta until the cord naturally separates. This is usually 1-3 days.
