Is the human fetus a parasite?
I saw this on yahoo:
FETUS IS NOT A BABY (GOOGLE THE HUMAN DEVELOPMENT CHART), but a parasite because the classification of the biological relationship that is based on the behavior one organism (fetus) and how it relates to the woman's body.
as a zygote, it invaded the woman's uterus using its TROPHOBLAST cells, hijacked her immune system by using NEUROKININ B and HCG--- so her body doesn't kill it, steals her nutrients to survive, and causes her harm or potential death.
"The placenta ,It secretes Neurokinin B containing phosphocholine molecules. This is the same mechanism used by parasitic nematodes to avoid detection by the immune system of their host."
"Due to its highly-negative charge, hCG may repel the immune cells of the mother, protecting the fetus during the first trimester.
"It is also possible for a symbiotic relationship to exist between two organisms of the same species."

just like a parasitic twin --- http://en.wikipedia.org/wiki/Parasitic_twin
"an animal or plant that lives in or on another (the host) from which it obtains nourishment. The host does not benefit from the association and is often harmed by it"

A parasite is a feeding relationship in which one organism(parasite) benefits at the expense of another organism(host). Eventually, a parasite usually will kill its host although it may take a long period of time. Parasitism occurs between organisms of two different species. For example, a hookworm can parasitize a human and use the human's blood for its nutrition. A tapeworm can attach to the intestine of a human host and absorb the human's digested food for its own benefit.
By definition, a human fetus can never be a parasite. Although it grows inside the uterus of its mother and relies on the mother for its supply of oxygen, food and removal of its wastes, it is the same species as its mother and cannot be a parasite. Most mammals have a gestational period where the embryo and later the fetus completes its development.
Mammals have a unique organ called the placenta which insures that the developing young gets all it requires to grow and thrive. An embryo is part of the life cycle of a human which is the reproductive phase. But just because the developing young relies heavily on its mother, it is not a parasite.
