Question

Quizplus · Accepted Answer

The placenta secretes human chorionic gonadotropin, estrogen, and progesterone to support fetal growth and development. Option B is incorrect as although the placenta does provide nutrients and oxygen to the fetus, it does not serve as a substitute for the respiratory, circulatory and digestive systems. Option C is incorrect as maternal and fetal blood supply is separate, but nutrients and gases can diffuse across the placental barrier between the two.
