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

Explanation

The embryo gets nutrition from the mother's blood with the help of a special tissue called placenta. Placenta is a disc-shaped tissue which is embedded in the uterus wall (uterine wall). It has villi on the embryo side of the tissue. On the mother's side are blood spaces which surround the villi. Placenta provides a large surface the tissue. On the mother's side are blood spaces which surround the villi. Placenta provides a large surface area for glucose and oxygen to pass from the mother to the embryo. The developing embryo also produces area for glucose and oxygen to pass from the mother to the embryo. The developing embryo also produces area for glucose and oxygen to pass form the mother to the embryo. The developing embryo also produces waste substances which can be removed by transferring them into the mother's blood through the placenta.
