"Person" and "human animal" are two different things. All human animals that have survived birth are, by nearly uncontested tradition and law, also persons. Unfortunately, so are some corporations. Fortunately, some technically living humans aren't -- e.g. Terri Schiavo.A "person" doesn't have the right to host on your body if you don't approve. To say that a fetus is a person is ridiculous.
Personhood is not biologically determined. It's not scientifically describable. It can't be measured or physically detected. It's a legally and ethically defined condition.
