It isn't. The rest of the body is small.
Several hundreds of millions of times larger in volume, if not even larger.
Cells of an embryo or fetus primarily undergo the mitotic cell cycle, consisting of G1, S, G2, and M phases, to create new cells for growth and development. In contrast, cells in an adult primarily undergo the G0 phase of the cell cycle where they are not actively dividing but can re-enter the cell cycle when needed for tissue repair or maintenance.
fetal hemoglobin differs most from adult hemoglobin in that it is able to bind oxygen with greater affinity than the adult form, giving the developing fetus better access to oxygen from the mother's bloodstream.
In the bones.
It takes a man and a woman to make any kind of human fetus.
A fetus is another name for an unborn baby, and growth is how it gets bigger.
From Fetus (egg), to adolescent, to adult
Pulmonary vein
After the first eight weeks, the embryo is referred to as a fetus. At this stage, the major organs have formed and the fetus continues to grow and develop until birth.
There are no products that use human cells, whether fetus, baby, or adult cells.
The human fetus has 275 bones, many more than the 206 bones found in the adult skeleton. This is because many of the bones described as single bones in the adult have not yet fully ossified and fused in the fetus. The skull's sutures do not close until after the infant ages. Adult sutures are fully closed.

There is no such thing as an adult baby. It would be the same as asking whether a teen fetus can run around in his house.
The embryonic period extends to the end of the eight week. After the embryonic period (8weeks), the developing human is called a fetus.
because fetal bones fuse together
A human fetus that is 26-29 weeks gestation has an average weight of 1110-1350 grams.
