Which of the following statements about the development of the foetus is not correct?
Answer Details
The statement that is not correct about the development of the fetus is: "The circulatory system of the fetus is directly connected to the maternal blood vessels".
Explanation: The circulatory system of the fetus is not directly connected to the maternal blood vessels. Instead, the placenta, which is attached to the uterine wall, acts as an interface between the fetal and maternal blood systems. The placenta enables the exchange of nutrients, oxygen, and waste products between the fetus and the mother's blood without their blood mixing. The umbilical cord connects the fetus to the placenta and serves as a conduit for the exchange of these substances.
