Answer 1

The correct option is D

It secretes oxytocin during parturition

Placenta facilitates the supply of oxygen and nutrients to the embryo and also the removal of carbon dioxide and excretory materials produced by the embryo. The placenta is connected to the embryo through the umbilical cord which helps in the transport of substances to and from the embryo. Placenta also acts as an endocrine tissue and produces several hormones like oxytocin, human chorionic gonadotropin (hCG), human placental lactogen (hPL), estrogen, progesterone etc.
