I have a link here that states that the contents of the uterus are tissue. Not a "baby"<quoted text>
(a) I did paste the link.
(b) Because the alternative is a dead baby.
Sometimes, an instrument called a curette is used to remove any remaining tissue that lines the uterus. It may also be used to check that the uterus is empty. When a curette is used, people often call the abortion a D&C dilation and curettage.
There you go.
