Question

1. Can we consider the embryo a parasite in a womans body? WHY or WHY not

Answer 1

The parasite is any species of an organism that lives in another species showing adverse effect on the host but is benefited by itself. The embryo or fetus is same organism's structure developing into offspring within the mother animals. The parasite intrudes the host body directly from outside and can invade by means of vector indirectly. The embryo is formed by union of gametes and develops within the mother. The parasite is nourished by host cells and tissues through direct contact living in cells, blood and tissues. The embryo held in a separate amniotic cavity in mother uterus . The embryo or fetus in the mother uterus connected to mother through placenta and umbilical cord and obtains the nourishment by indirect contact. The embryo is result by the union of host gametes and parasite is not required for host cell reproduction rather it uses host cell mechanisms for its reproduction. The parasite may survive within the host body till the cells die. The embryo completes developemnt within a ceratin time period and expelled out after completion of development. Therefore, the embryo is the developmental structure and cannot be called as parasite in the woman's body.
