Question
Give reason.
Placenta is extremely essential for foetal development.
Solution
The placenta helps the growing embryo acquire nutrients from the mother's blood. The placenta has villi on the embryo's side of the tissues and blood spaces on the mother's side. These villi have a vast surface area, which aids in the transport of nourishment and oxygen from the mother to the foetus through blood. Waste substances created by the embryo are eliminated into the mother's blood via the placenta. Therefore, Placenta is extremely essential for foetal development.
