Answer to Question 1

ANS: B
The placental barrier protects the embryo/fetus from most bacteria, but not from viruses or drugs. The cotyledons are sections that make up the placenta. The chorionic villa are tiny vascular projections on the chorionic surface that help form the placenta.

Answer to Question 2

ANS: C
The placenta functions as an endocrine gland, secreting estrogen, progesterone, and HCG.
