Placenta consists of blood vessels which transfer nutrients and gases like oxygen from mother’s blood to foetus and excretory material from foetus to mother.

Answer 2

The developmental stages of a baby right from conception to the birth of the child are predictable. Things start as the cells begin to divide. They differentiate and form a zygote. After the formation of the zygote, the blastocyst is formed. It is from the blastocyst that the embryo is formed. After this, the fetus develops. All these changes occur in the first thirteen weeks of pregnancy itself. Right from the start, the cells require nutrients and oxygen to develop and divide. It is the placenta and the umbilical cord that work as the connecting link between the fetus and the mother. They transfer the nutrition to the baby from the mother
