Question

what is the difference between function of placenta and umbllical cord

Answer 1

Placenta is the tissue where maternal and foetal blood come in contact, and nutrients and oxygen are transferred from maternal blood to foetal blood while waste products are transferred from foetal to maternal blood.

On the other hand, Umbilical cord is a tube like structure (made up of one vein and two arteries) that act as a connection between foetus and placenta, and transfer the foetal blood to placenta.

Answer 2

Placenta is the place where nutrients and wastes are exchanged between mother and fetus, whereas umbilical cord serves as the link between fetus and placenta.
