Question

How does the embryo get nourishment inside the mother’s body? Explain the structure and function of the tissue involved.

Answer 1

Answer:

Embryo derives its nourishment from the mother's blood through the placenta. Placenta contains villi on the side of the embryo and blood vessels surrounding villi on the side of the mother. Oxygen and glucose pass from the mother to the embryo through the placenta.

The embryo gets nutrition from the mother's blood with the help of a special tissue called placenta. This is a disc-like tissue which develops between the uterine wall and embryo.

As mother eats, the food passes through the digestive system where the body breaks it down into small particles. These nutrients travel through the mother's blood stream and get exchanged with the blood stream of foetus through placenta.
