Deflection, and yes it is.
I asked WHY.
Of course not. BUT I know where you're going with this. And no, a woman does not have the right to kill a baby just because it is inside of her body. Let me explain: the kidney is an organ designed to filter blood and produce urine. Fairly simple. The uterus, however, is designed to nurture an unborn child. It's naturally ordered to do so. Unlike your kidney example, where I fall to save someone, abortion involves separation a healthy child from what he needs to live. Also, the person who is the forced donor presumably has nothing to do with the cause of the sick persons dilemma, and I'm assuming they are unrelated. But in the case of pregnancy, how did the unborn baby get there? Ninety-nine percent of the time, it is because the woman engaged in sexual intercourse, which has the effect of creating a dependent person in the womb. She should therefore be obligated to care for said child, since she was involved in his creation.
