Answer 1

¤ Placenta :

• It is a disc shaped structure which is embedded in the uterine wall of females.

• It develops during gestation period.

• It contains villi on the embryo's side of the tissue.
On the mother's side are blood spaces, which surround the villi.
This provides a large surface area for glucose and oxygen to pass from the mother to the embryo.

• It is mainly for providing nutrition to the growing embryo..

• It is also helpful in excretion as the waste generated by the developing embryo can be removed by passing or transferring them into mother's blood through placenta.
