That's what an aborted fetus looks like. Yes, most of the time it's not just a "clump of cells"

Most abortions are in the first trimester. A 12-week fetus, the last week in the first trimester, is the size of half-eaten corndog. That's not even close to a fully-formed baby, which is the size of a watermelon, and can survive independently of medical intervention.

The fetal cadaver in Father Pavone's video looks to be past the middle of the second trimester. Only 12% of abortions occur after the first trimester. Father Pavone got the cadaver from a pathologist. A second trimester cadaver in pathology means that there was something wrong, and the parents wanted to know if there's a higher-than-normal chance of birth defects or other abnormalities. If the medical team had tried to intervene, the baby most likely would not have survived at this stage, and even the Catholic church does not support futile medical intervention. Even with intense medical intervention, less than 1/4 of neonates born at 22 weeks survive. Based on the circumstances, it's likely that something was wrong with the fetus, which further reduces the chance of survival. In addition to looking at survival, a 22-week fetus is far from "fully formed," which is why even neonates born at 22 weeks who survive are much more likely to have health problems than an actually fully formed baby, with a full-term birth.

The fetus in Father Pavone's video was clearly intact, and he describes prostaglandin-induced labor. Dismemberment in abortion is a legal requirement, not a medical requirement. Intact dilation and extraction is actually safer for the pregnant woman. Induction is used rarely in abortion and is more commonly used after a miscarriage, to remove the dead baby. An intact fetal cadaver in the pathology department, from a pregnancy that was induced early, could be from an abortion, but is more likely a miscarriage. It is clear that you have no idea what you are talking about.
