the Umbilical Cord vs Placenta: Difference and Comparison

Giving birth to a baby is the hardest thing to do. A woman has to carry the baby for almost 9 months in her womb before giving birth.

The emotional and physical connection of the mother with the baby cannot be expressed in words. The umbilical cord and placenta play a significant role in guaranteeing the fetus’s survival inside the womb.

Key Takeaways

  1. The umbilical cord connects a baby to the placenta, facilitating the transfer of nutrients, oxygen, and waste.
  2. The placenta is an organ that develops during pregnancy and plays a crucial role in nourishing and protecting the fetus.
  3. After birth, the umbilical cord is cut, and the placenta is expelled from the mother’s body.

Umbilical Cord vs Placenta

The difference between the umbilical cord and the placenta is that the umbilical cord forms a connection between the emerging fetus and the placenta, which is one of the major organs of the mother, whereas the placenta is a transient part that helps in connecting the mother and the fetus.

Umbilical Cord vs Placenta

The umbilical cord is also popularly known as the birth cord. The umbilical cord has two ends; one is attached to the fetus, and another is to the mother’s placenta.

The development of the umbilical cord takes after the 5th week of conception and develops until the 27th week of pregnancy.

The placenta is one of the most vital organs that helps in transferring minerals, nutrients, and oxygen from the mother to the fetus for its survival and growth.

One of the major features of the placenta is that it produces hormones of different kinds. Placenta also removes and filters out all the waste from the mother’s blood so that it does not harm the fetus.
