The placenta is connected to the embryo through an ul((A)) .

The placenta is connected to the embryo through an ul((A)) .

Umbilical cord helps in the transport of substances to and from the embryo. Which among these is not a function of the umbilical cord:

(a) How is the placenta connected to the embryo? (b ) Placenta acts as an endocrine gland. Explain.

Assertion : In placental mammals the placenta is connected to the embryo by the umblical cord and has an essential role in the immunological protection of the embryo . Reason : In mammals foetal components of the placenta derive initially from the chondroblast connected with embryonic derive initially from he chondroblast connected with embryonic blood stream either through its contact with the yolk sac.
