Solution 1

Placenta is the connecting link between the mother's body and the baby. It is a disc embedded in the uterine wall. This special tissue contains villi on the embryo’s side of the tissue and 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 baby. The developing embryo generates certain waste substances that can be removed through placenta.

Solution 2

Function of Placenta:-

The exchange of materials between the mother’s blood and the blood of foetus takes place through placenta. It serves as a nutritive, respiratory and excretory organ of the foetus.

Solution 3

The embryo gets its nutrition inside the uterus with the help of a special tissue, called placenta. Placenta is a disc of specialised tissue embedded in the uterine wall and serves as the connecting link between the mother's body and the baby. It contains blood spaces on the mother's side and thousands of villi (small projections) on the foetal side that provide a large surface area required for the exchange of nutrients and oxygen between the mother and the foetus. The wastes produced by the foetus are also removed through the placenta. It also functions as an endocrine gland and secretes hormones necessary for maintaining pregnancy
