How does the embryo get nourishment inside the mother's body ?

Text Solution

Verified by Experts

After fertilization the lining of the uterus thickens and is richly supplied with blood to nourish the growing embryo. The embryo gets nutrition from the mother.s blood with the help of a special tissue called placenta .It is embedded in the uterine waIL. On the embryo.s side of the tissue lie the villi and on the mother.s side lie blood spaces. The blood spaces surround the villi. The placenta works as a channel between the mother and the embryo. Nutrients and oxygen are supplied to the embryo through this. Additionally, excretory products from the embryo are removed through the placenta.
