Question

How does the embryo get nourishment?

Answer 1

Embryo:

1. Embryo refers to the early-stage development of organisms.
2. In sexual reproduction, fertilization is followed by multiple stages of embryonic development.
3. The zygote formed as the product of fertilization is referred to as an embryo until the ninth week after fertilization.

Nourishment for the embryo:

1. The embryo receives nourishment from the mother via a tissue called the placenta.
2. Placenta connects the embryo to the uterine cavity of the mother via the umbilical cord.
3. The placenta contains villi on the side exposed to the embryo and the mother's blood vessels surround the villi.
4. The mother supplements the embryo with oxygen and glucose for its growth and development.
5. The wastes generated by the embryo are transported to the mother's blood via the placenta.
